x ZIP4x5 User’s Manual

1 Chapter 1Introduction1.1 Scope1.1.1 AudienceThis manual is intended for networking engineers and network administrators who need toinstall, maintain, support, and use the ZIP4x5. The manual can also be used by engineers thatwant to make a phone system compatible with the ZIP4x5. The manual assumes you are familiarwith networking and telephony principles and practices.If you are using the ZIP4x5 with the MX250 or the MX1200, you should read this manual inconjunction with the MX Administrator User’s Manual.1 That manual describes how certainfeatures of the phone interact with the enterprise media exchange. You can obtain that manual online at one of these web sites:http://www.MX250.comhttp://www.MX1200.comThis manual on the ZIP4x5 can be used by a user who wants to understand in detail how featuresand functions of the phone operate. End users who do not need the depth of informationcontained in this manual (which is about 150 pages) should refer to the ZIP4x5 User’s Guide(which is 12 pages). One guide is shipped with each phone, but you can download the guide fromthe ZIP4x5 web site at:http://www.zip4x5.com1.1.2 Installation and UseUnpack the ZIP4x5 and verify the contents as described in section 3.2 on page 17. Install theproduct as described in chapter 4, starting on page 21.1.1.3 What this Manual IncludesThis manual provides detailed information and instructions on the complete installation andoperation of the ZIP4x5 IP phone.1. The MX250 and MX1200 are Enterprise Media Exchanges. They are manufactured by Zultys and provide the commu-nications needs of an enterprise by integrating voice, data, video, and fax.

Access the Zultys web site for this information:http://www.Zultys.com1.2 FeaturesThe ZIP4x5 is a SIP based IP phone with a large number of features. The top of the phone isshown in figure 1-1 and the bottom of the phone in figure 1-2. The phone is referred to as a “fourby five” because it has four call appearances and five circuits – four Ethernet circuits and oneanalog circuit. Key features of the phone are:•four virtual lines support four simultaneous calls•headset, handset, and speaker modes•acoustic echo cancellation in speaker mode provides high quality speaker phoneFigure 1-1 Top View of ZIP4x5

1. Introduction3•four 10/100Base-T Ethernet circuits to connect to the LAN and three additional devices such asa desktop PC, a notebook PC, and another accessory•one analog circuit to connect to the PSTN•supports all commonly used PBX functions when used in conjunction with an appropriate callcontrol system•supports IEEE 802.1q VLAN tagging and IEEE 802.1p priority marking so it can be used withany switch•receives power over Ethernet (IEEE 802.3af) or from ac adapter•speech encryption ensures that your calls can be kept secure•easy to create conferences with three to five people, including those who call you•35 buttons (11 with LEDs) give significant ease of use•3 line x 20 character display is easy to read (5 mm high characters)•uses standard SIP messages to interface to a variety of call managers from variousmanufacturers•dial by number or SIP address•built in switch can forward traffic at line speeds and supports QoS and VLAN tagging•complete calculator functionFigure 1-2 Bottom View of ZIP4x5

4ZIP4x5 User’s Manual•hot key dialling•voice activated dialling•firewall, NAT, VPN, and DHCP server functions•STUN protocol support•PPPoE support for connecting to WAN•Bluetooth support for wireless headsets•browser and TFTP support for configuring and updates•critical operational parameters are protected by password•100 memory phone book plus 64 location memory for last numbers received or dialled•based on highly stable Linux operating system1.2.1 Switch FunctionalityThe phone uses an Ethernet switch (not a hub) to connect the three accessory ports and the phoneitself to the LAN. Therefore, the ZIP4x5 can control the QoS to ensure that voice packets alwayshave priority. Further, when the phone is not in use, the ZIP4x5 supports wire speed switchingbetween the LAN (network) and the accessory ports. A conceptual picture of the switch is shownin figure 1-3.Figure 1-3 Internal Representation of the Managed Switch

1. Introduction5You can put the phone and the accessory ports on different VLANs (802.1q – see section 10.6.4 onpage 173 for details).The inclusion of the switch inside the phone allows you to take a single Ethernet circuit from thewiring closet to the desktop. If you are connecting multiple users and not computers, you can usethis internal switch to make connections to other phones. You can connect phones two layersdeep with this arrangement to minimize the number of switch ports required in the wiring closet.1.2.2 Display DescriptionThe display is a graphical LCD, 160 dots by 32 dots.

22ZIP4x5 User’s Manual4.2 Preparing the ZIP4x5 for Use4.2.1 HandsetConnect the handset to the bottom of the phone as identified in figure 1-2. Trap the cord in theclips at the back of the phone to relieve strain on the connector and to allow the cord to exit neatlyto the left of the phone.4.2.2 PowerYou can power the ZIP4x5 from an ac supply or from the network.4.2.2.1 Power over EthernetIf you ordered the phone without an ac adapter you must ensure that you connect the ZIP4x5 toan Ethernet switch that provides power as per IEEE 802.3af.1 The ZIP4x5 takes its power from theport labelled LAN. The cable length can be 100 m, the maximum allowed for an unpoweredEthernet circuit.4.2.2.2 Power from an AC AdapterIf you have ordered the phone with an ac adapter, you should use it regardless whether power isprovided over the Ethernet connection. Connect the ac adapter to the bottom of the phone asidentified in figure 1-2. The plug is at a right angle to the cord so that if you accidentally pull thephone, the cord does not fall out.24.2.2.3 Dual Power SourcesIf the phone receives power from both the Ethernet port and an ac adapter, it consumes poweronly from the ac adapter. You can see what power is applied to the ZIP4x5 using the menu. Seesection 10.4.3 on page 144.If the ac power fails, the phone can take power from a LAN power source and continue to operate.The length of time that the phone will operate with the power from the LAN is dependent on thecapacity of the battery connected to the power source and the number of phones drawing power.Using the phone to make a call does not materially change the power used by the phone.4.2.2.4 When Power is AppliedWhen you apply power, the phone starts to operate. The ZIP 4x5 does not have any power switch.After the phone is powered up, it displays a message on the screen as shown in section 4.3 on page26.1. The ZIP4x5 is fully compliant with IEE 802.3af and is a device that consumes “half power” as defined by the specifica-tion.2. You should use one of the ac adapters provided by Zultys. If you are unable to obtain this, use an adapter that has a dcoutput of 12 V, 600 mA. The plug should be 2.0 mm or 2.1 mm with the center positive.Zultys does not warrant operation of the ZIP4x5 with any adapters other than those supplied by Zultys.

4. Installation234.2.3 Wall or Desk MountingYou can mount the phone on a wall or on a desk. Install the rear platform that has the two backfeet if you are putting the phone on a desk. Remove this platform (as shown in figure 1-2) if youwant to mount the phone on the wall, and mount it in the lower position.4.2.4 Connecting to the NetworkYou normally connect the ZIP4x5 to a LAN or directly to a call control system. The call controlsystem manages many function for the phone including the ability to originate and terminate acall, and provides a storage for voice mail. This section briefly describes the process of connectingthe phone to a network.Section 9.2.9 on page 105 describes the method of directly connecting two ZIP4x5 phones, eitheroutside of a LAN or isolated within a network.4.2.4.1 Auto MDI/MDI-X and Auto NegotiationEach of the four Ethernet circuits on the ZIP4x5 has automatic sensing to determine on whichpins of the RJ45 connector it should transmit data and on which pins of the RJ45 connector itshould receive data. This is referred to as auto MDI/MDI-X.With this function in the phone, you can use a straight or cross wired cable to connect the phoneto any other device. If you connect the phone to a device that itself has auto MDI/MDI-X, thedevices resolve the appropriate pins to use through random selection.Also, each of the four Ethernet circuits on the ZIP4x5 has automatic sensing to determine whetherthe circuit should operate at 10 Mb/s or 100Mb/s. The phone will always attempt to establishconnection at the higher rate and will fall back to the lower rate only if the device to which youhave connected the phone cannot operate at the higher rate.4.2.4.2 Single CircuitConnect the LAN circuit on the back of the phone to the LAN, as shown in figure 4-1.You may have a router or switch to which you connect the phone. Whatever connectivity existsbetween the phone and the SIP server, ensure that you use the LAN port to perform the uplink.1Connect your PC or notebook to any of the other three circuits (P1, P2, or P3). You can identify ifthe phone has connectivity and activity on any of the circuits as described in section 10.4.3 onpage 144.4.2.4.3 CascadingThe ZIP4x5 has a very efficient network switch incorporated in it so you can cascade the phonesas shown in figure 4-2.1. If you do not use VLANs on the phone, and if you do not expect the phone to receive power from the network, you canactually use any port to connect to the phone system. In this case, the switch inside the ZIP 4x5 is an unmanaged switchand it does not matter to which port you connect. However, the phone must have connectivity on the port marked LANand always using this to connect to the network ensures that you have a consistent network that is easier to maintain.

You can also use a Bluetooth wireless headset with the ZIP4x5. The most convenientsolution is the wireless headset while the lower cost alternative is a headset on the side of thephone. Audio socket output parameters include:•Rated Output: 12.5 mW•Impedance (ZL): 32 ohms•Microphone Type: condenser•Connector Type: 2.5 mm mono phone jack Tip – MicrophoneRing – SpeakerSleeve – GroundZultys supplies a headset with the phone, but you can buy good quality replacement headsets forabout $20. Traditionally, headsets have been designed to plug in series with the handset. These also providegood quality but typically cost $120.With the ZIP4x5 you can choose either type of headset. Switching between the headset, handset,and speaker is described in section 9.1.1 on page 97.4.2.5.1 Using a Wireless HeadsetThe ZIP4x5 supports all Bluetooth wireless headsets. Section 10.5.7 on page 155 describes theprocedure for programming the phone to recognize your Bluetooth headset and to pair yourheadset with the ZIP4x5.4.2.5.2 Using the Audio ConnectorThe connector on the side of the phone is a 2.5 mm socket. Connect the headset that came withthe phone or an alternative standard headset into this socket.Do not buy a headset that has two connectors. These are normally used to connect to the soundports of a PC. Those connectors are 3.5 mm.4.2.5.3 Using an External Switch BoxYou can connect a headset in series with the handset connector as shown in figure 4-4. The switchbox usually has an amplifier that is powered either from an ac outlet or from batteries. This boxallows you to select between using the handset and using the headset.

37 Chapter 5Provisioning the Phone5.1 IntroductionThis and the following sections (section 5.2 through section 5.4) describe the methods used by theZIP4x5 to automatically obtain its configuration. These sections describe the underlying methodfor the exchanges that take place. You do not need to read these sections unless you want tounderstand the provisioning process, or make the ZIP4x5 work with a particular SIP system.5.1.1 Summary of Boot ProcessTo use the ZIP4x5 in its usual manner, you must connect the phone to a LAN that has a DHCPserver and a TFTP server. The start up process is as follows:1. The DHCP server provides an IP address to the phone and also the address of the TFTPserver.2. The phone accesses the TFTP server to locate a configuration file that is common for allZIP4x5 phones connected to your network. 3. The phone reads the common configuration file. The configuration file points to a directorywhere the phone can find its specific configuration file.4. The phone reads its specific configuration file. 5. The phone uses the data retrieved from the configuration files to configure itself so that itcan operate properly in the network.5.1.2 DHCP SupportWhen you connect the ZIP4x5 phone to a DHCP server, the DHCP server must be configuredwith the following options for your network to fully support the ZIP4x5:•subnet mask (option 1)•default gateway (option 3)•domain name server (option 6)•IP Address (option 50)•TFTP server name (option 66)In addition, it is recommended that your DHCP server also provide:•NTP Time Offset (option 2)

38ZIP4x5 User’s Manual•domain name (option 15)•NTP servers (option 42)You should consult your system administrator for specific details on configuration of the DHCPserver.5.2 Configuration FilesThere can be three sources of configuration for the phone:•what is saved in a common configuration file•what is saved in a specific configuration file•what is saved in the phone’s memoryThe common configuration file is called:ZIP4x5_common.cfgThis file is stored in the root directory of the TFTP server.The specific configuration file is called:<MAC address>.cfgFor example,0050C2180FD8.cfgThe format for the files is identical, and is shown in figure 5-1. This is an ASCII text file, with thename of the parameter and the value of the parameter listed on the same line. Each parametermust be within the section (denoted by square brackets “[]”). The contents of the file are not casesensitive; you can enter parameter names in upper or lower case. Comment lines are denotedwith a leading semi-colon (;) and have no effect on the operation of the phone.[HW_CONFIG]lcd_contrast=8ring_volume=5speaker_volume=5headset_volume=5handset_volume=5Figure 5-1 Format for Configuration File

40ZIP4x5 User’s ManualMany parameters in the configuration files correspond to the parameters that you can configurethrough the menu of the ZIP4x5. Configuration parameters are described in Appendix C, startingon page 197.Every time the phone restarts (either by command or by power on), the phone reads theconfiguration files. It extracts the data in the files and saves it to memory, overwriting allparameters that are saved in memory except that if the user settings are not configured to becleared, it retains the settings in the phone.1The common configuration file specifies a directory, using the parameter:2tftp_cfg_dir= <directory_name>The phone accesses the specified directory (which can be blank, or ‘.’) and reads the specificconfiguration file from the specified directory. It extracts the data in the file and saves it tomemory, overwriting whatever parameters were already saved in memory. The parametersspecified in the specific configuration file take precedence over the same parameters specified inthe common configuration file.For example, suppose the common configuration specifies the greeting message to be:[AUDIO_INFO]ext_ring_tone=0ext_cust_ring=int_ring_tone=0int_cust_ring=ring_tone2=0cust_ring2=key_click=0codec=0distinctive_ring=yesaccept_url=nosound_url=[GENERAL_INFO]software_version=1.0.0;The message displayed on the LCD in idle modegreeting_message=ZIP 4x5 SIP Phonepassword=985897time_fmt=%H:%Mdate_fmt=%a %d %b %ydate_time_order=0;This is the offset from GMT, in minutestimezone=-480country=USAlanguage=ENGLISHdelmtr=._clear_settings=21.

Through this utility, you can modify all operating parameters that areavailable through configuration files. To access the web interface, enter the IP address of your ZIP4x5 in the address entry box of yourweb browser and press the enter button. The home panel will appear in your browser.Appendix D, starting on page 225, describes each panel of the web interface configuration utility.5.4 Updating Software on the ZIP4x55.4.1 IntroductionYou must connect the phone to a LAN that has a TFTP server and a DHCP server.1 The DHCPserver provides an IP address to the phone and also the address of the TFTP server. The phoneaccesses the TFTP server to locate and retrieve its configuration files. It reads the configurationfiles to identify what software version it should be using. If the files specify a different versionfrom that on the phone, the phone retrieves the specified software version from the TFTP server.5.4.2 Specific DescriptionTo update the software, one or both of the configuration files described in section 5.2 must specifythe software version that the phone must use. This is specified on the line shown in figure 5-2 as:software_version=0.1.4The phone compares the version specified to that installed on the phone. If the versions are thesame, the phone continues with the startup process. If the versions are different, the phoneretrieves the software from the TFTP site. The phone looks first in the root directory of the TFTPsite then in the subdirectory of the TFTP site where the specific configuration file may be stored,if one is specified.Freddy PhoneWed 20 Nov 02 14:501. You cannot update the software if you fix the IP address of the phone.

When the ZIP4x5 reads the file, itverifies the version that is contained in the file with the file name and will not load it if theversions do not match.The first characters in the binary file are encoded as a null terminated ASCII string. The end of thefile contains a 16 bit CRC sum check.The size of the binary file is between 2 MB and 4 MB.5.4.4 Ladder DiagramFigure 5-2 shows the messages used in this process. The following sections describe the process.5.4.4.1 Step 1Action. ZIP4x5 sends DHCP DISCOVER (broadcast)Description. The ZIP4x5 boots (after power is initially applied or after receiving a SIP NOTIFYmessage) and sends out a DHCP DISCOVER message requesting an IP Address and other options(same as those provided in DHCP ACK).5.4.4.2 Step 2Action.

The ZIP4x5 receives TFTP data (ZIP4x5_version.bin) from the TFTP ServerDescription. After downloading the software version the ZIP4x5 reboots and repeats all of thesteps (except for retrieving software). At this point, the ZIP4x5 performs a checksum verificationand compares the new software version file name with the version information stored internallyto the .bin file. If the checksum fails or if the file name does not match that of the versioninformation stored internally to the .bin file, the phone indicates an error and loads the previoussoftware version.

5. Provisioning the Phone 455.4.5 SummaryFor a user, the process of updating the software is fully automatic. The administrator of thenetwork can initiate this process at any time. When the phone is idle, it will start the process ofupdating the software. Usually, the administrator would cause this to happen when no one islikely to want to use the phone.To start the update process, the software in the phone restarts and displays:The phone displays this message using different characters than normal, and only two lines oftext. It shows the progress of the update on the second line using periods (full stops). There are20 characters on the line and each period indicates the phone has completed about 5% of theprogramming task. The phone shows a new period every one to three seconds.Important Do not disturb the phone during the update process. You cannot use the phoneto make or receive calls while the software is being updated. This process takesabout 30 seconds.When the phone has provisioned the software, it restarts itself, just as it does when you power iton. After about 15 seconds the phone displays the idle display and is ready to use.If the software update process fails, the phone may display:The phone displays this message if it found the software file but the file had been corrupted.Contact the system administrator to resolve this.

47 Chapter 6Interacting with the Phone6.1 Call AppearancesThis ZIP4x5 is different from phones that have been in common use for the past 100 years. Onolder phones a physical pair (or two pairs) of wires carry a single voice call. A phone that canaccommodate two voice calls connects to two such circuits, with each circuit being referred to asa line. A switch on the phone selects between the lines (and therefore with whom you are talking).A phone that has four lines has four such sets of circuits and can allow four simultaneous calls.The ZIP4x5 connects an ethernet circuit and an analog circuit to the switch. All digital calls takeplace over one ethernet circuit, or line. Dedicated software and hardware inside the phone andthe switch permit you to have four simultaneous conversations. The analog circuit carries a singlevoice call.The ZIP4x5 has four call appearances. Each call appearance allows you to have a separate orjoined call. Each call appearance can carry a single voice calls. Call appearances one, two, andthree carry calls from the ethernet circuit. Call appearance four can carry calls over the ethernetcircuit or the analog circuit. If the analog circuit is connected directly to the PSTN, it will have adifferent phone number than the digital call appearances. The digital and analog circuits can beprogrammed to the same phone number and extension if the ZIP4x5 is connected to a mediaexchange system that supports digital and analog calls.6.2 Using the Keypad and the ButtonsThe term buttons refers to the switches that are identified by the writing on a label below them,shown in figure 6-1.The term keypad refers to the switches that have writing on them, shown in figure 6-2. 6.2.1 Description of Keypad6.2.1.1 Numerals and Dedicated KeysThe keypad has keys labelled 0 to 9, *, and #. These are used to dial a number and perform otherfunctions. The keypad has keys that are dedicated to specific purposes identified by the text onthe key.

48ZIP4x5 User’s Manual6.2.1.2 Function KeyThe keypad has a key marked Func that serves as a function, or shift, key to select alternative usesfor the keys and buttons. To select the alternative use, press and release the Func button once,then press the appropriate button or key to select the alternative function.Important Do not press the Func key and another button or key simultaneously. The ZIP4x5can read only a single button or key being pressed at a time.Figure 6-1 View of Buttons on ZIP4x5Figure 6-2 View of Keys on ZIP4x5

6. Interacting with the Phone 49The Func key is green and the label on the card that shows the alternative function of the buttonis also green. If you cannot distinguish between these colors, the alternative use is written to theright of the standard use.For example, to select the calculator mode, press Func then the button marked Mem and Calc. Toexit calculator mode, repeat this sequence. In subsequent sections of this document, the text doesnot describe this sequence. That is, the text states, for example:“To enter calculator mode, press Calc”This saves writing:“To enter calculator mode, press Func then Mem | Calc”6.2.1.3 Volume KeysThe volume keys are identified by the double arrows on the wide button. You press the up arrowto increase the volume and the down arrow to decrease the volume. The keys are used for otherfunctions depending on the mode.When you change the volume, the phone remembers the value you set and uses it in the future.When you power down the phone and restore power, the phone retains the same setting. Thereare five individual volume settings:1. When the phone is idle, the volume keys control the volume of the ringer. When you pressthe keys, the phone plays the ringer tone that you have currently selected. You can adjustthe volume to suit your needs. After you stop pressing the key, the ZIP4x5 continues to playthe ringer tone for two seconds.12. When you are using the handset, the volume keys control the volume at which you hear thespeech from the other party through the earpiece.3. When you are using the headset as shown in figure 4-3 on page 26, the volume keys controlthe volume at which you hear the speech from the other party through the earpiece.4. When you are using the headset as shown in section 4-4 on page 26, the volume keys controlthe volume at which you hear the speech from the other party through the earpiece.5. When you are using the speaker, the volume keys control the volume at which you hear thespeech from the other party through the speaker.When you adjust the volume of the headset, ensure that you have the handset on the cradle. Thephone adjusts the level for the correct external headset (through a switch box or through an audioconnector) depending if you have plugged a headset into the audio connector or not.Each volume control has twenty one settings, numbered 0 to 20. When you adjust the level, thedisplay shows:The bar at the bottom of the display represents the volume graphically, from 0 to 20. When thevolume is at 0, the sound is completely turned off.1.

You usethe buttons labelled Call 1, Call 2, Call 3, and Call 4 to make, receive, and terminate calls. The othereleven buttons have two purposes, depending if you pressed the Func key before you pressed thebutton.1To access the secondary function of a button, press and release Func then press the button. If youdo not press a button within 2½ seconds, the shift function is inoperative, so that when you pressa button you will select the standard use for the button not the secondary function.If you select the Func key in error, you can cancel it by pressing Func again.When you press the Func key, it does not lock the selection of secondary use of the buttons.2Therefore, if you want to select another secondary function, you must press the Func buttonagain. For example, suppose you want to enter calculator mode and then want to pick up apreviously parked call. You would press:Func, Mem | Calc, Func, Park | PickupYou use the top row of buttons to navigate the menu as described in section 6.3.3 on page 51.When you press Func before you press one of the buttons on the top row, the phone dials anumber that you have stored in memory locations 01 to 05.3The use of each of the buttons is described in later sections.6.3 Basics of Display OrganizationThe LCD is used to display information and configuration.The top row of buttons provide access to the menu so you can configure the phone. From themenu you can also view information about the phone. Some buttons directly affect the operationof the phone or the way the phone interacts with the phone system.As you make or receive calls, or affect the operation of the phone, the LCD shows the status of thecalls or interaction with the system.6.3.1 IdleWhen the phone is idle:•each of the call appearance LEDs is off•the phone displays a greeting message on the first row of the display•the phone displays the date and time on the third row of the display1. The Func key is described in section 6.2.1.2 on page 48.2. This behavior is different from when you are dialling and use the Func key to select alternative use for the keys.3.

Your phone can make calls only to devices that also support encryption. Your phonecannot make a call to, or receive a call from, a device that cannot encrypt the speech. Youcannot turn off encryption during a call.•If the phone is configured so that you have control over the encryption (normally on ornormally off), your phone can communicate with devices that support or do not supportencryption. You can use the Encrypt button to engage or stop encryption. If you make a callto a device that does not support encryption, and you have requested that the call beencrypted or your phone by default is trying to engage encryption, the call will complete withencryption disabled. You can engage and stop encryption during a call.The phone tries to establish all calls to be encrypted if configured for normally on. You canturn off encryption before or during the call.The phone tries to establish all calls to be without encryption if configured for normally off.You can turn on encryption before or during the call. •If the phone is configured so that encryption is never on (cannot be engaged), pressing theEncrypt button has no effect. Your phone can make calls only to devices that are do not requireencryption. Your phone cannot make a call to, or receive a call from, a device that alwaysencrypts the speech. During a call, your phone will reject a request by the far end to engageencryption.Regardless of the setting chosen by the administrator, the LED on the Encrypt button is off whenthe phone is idle. It becomes active only during a call as described in the sections below.ZIP4x5 encryption is based on open standards. To encrypt the conversation, each person must beusing a device that supports these open standards, such as another ZIP4x5 or compatible phone.The encryption is completely loss-less. That is, the quality of the voice is the same whether thevoice is encrypted or not. The encryption introduces negligible delay to the speech. When youswitch between the call being encrypted or not encrypted, the ZIP4x5 performs this almostinstantaneously, but can take as long as 200 ms if there is a lot of traffic on the network.Ensure that you understand the various ways to originate and terminate a call as described insection 9.2 on page 99 and section 9.6 on page 120 before reading the remainder of this section. Ifyou want to create a conference call with encryption, ensure you know how to use the conferencefunctions as described in section 9.8 on page 126.7.2.2 Individual Calls7.2.2.1 Making a Call When Encryption is Always OnWhenever you select a call appearance (directly or indirectly) to make a call, the LED on theEncrypt button flashes green synchronously with the green LED on the call appearance button.If the device that you are calling supports encryption, the call completes as normal and the ZIP4x5lights the LED on the Encrypt button continuously green.1.

7. Special Functions 597.2.3 Holding, Parking, Transferring, and Forwarding CallsWhen you put a call on hold or park it, the other person’s device now communicates with the callmanager system, whereas it previously communicated with your phone. Similarly, when youtransfer a call or forward a call, the other person’s device now communicates with someone else’sphone.In each of these cases the encryption policies of the devices have to be compatible or the call maybe dropped.For example, consider the case when you are speaking with a person who puts the call on hold:•If your phone is configured for normally on or normally off, it will adapt to the new speechpath coming from the phone system by either engaging or turning off encryption.•If your phone is configured for always on or never on, the phone system must supportencryption in the former case or must be able to establish communication without encryptionin the latter case. If the phone system cannot communicate with your phone, your phonerejects the call and your conversation is not placed on hold. Depending on the phone systemyour call may then be dropped or the phone system may reconnect you to the other person.If you put a call on hold successfully, the phone turns off the LED on the Encrypt button. If thephone system rejects the call and does not return the call to your phone, the call will be droppedand the ZIP4x5 will turn off the LED on the respective call appearance button.7.2.3.1 Transferring CallsTo transfer a call, you place the active call on hold, then dial the person that will receive the activecall, as described in section 9.5.3 on page 118. If encryption on each phone is set for normally onor normally off, the encryption state of the transferred call depends on your call to the person thatwill receive the transferred call. After placing the active call on hold:•if you call the person that will receive the active call with encryption on, then the transferredcall will be encrypted•if you call the person that will receive the active call with encryption off, then the transferredcall will not be encrypted.7.2.3.2 Forwarding CallsCall forwarding routes incoming calls to another destination, as described in section 7.5 on page65. If encryption on each phone is set for normally on or normally off, the encryption state of theforwarded call depends on the encryption setting of the phone initiating the call. 7.2.4 Conference Calls7.2.4.1 GeneralAll calls that comprise a conference call must be encrypted or not encrypted. You cannot mix callson a conference call that are encrypted or not encrypted because this makes the entire conferencesubject to eavesdropping and is therefore not secure.
