P a g e | 31 HT81x User Guide CALL OPERATIONS Placing a Phone Call To make the outgoing calls using your HT81X 1. Pick up the handset of the connected phone. 2. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or 3. Dial the number directly and press # (Use # as dial key” must be configured in web configuration). Examples: 1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds. 2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers. Direct IP Calls Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy. Elements necessary to completing a Direct IP Call:  Both HT81X and other VoIP Device, have public IP addresses, or  Both HT81X and other VoIP Device are on the same LAN using private IP addresses, or  Both HT81X and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ). The HT81X support two ways to make Direct IP Calling: Using IVR 1. Pick up the analog phone then access the voice menu prompt by dialing “***” 2. Dial “47” to access the direct IP call menu 3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling” Using Star Code 1. Pick up the analog phone then dial “*47” 2. Enter the target IP address.

P a g e | 32 HT81x User Guide Note:No dial tone will be played between step 1 and 2 and destination ports can be specified using “*” (encoding for “:”) followed by the port number. Examples of Direct IP Calls: a) If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 47, then 192*168*0*160, followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is used if no port is specified b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be: *47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds. Note: When completing direct IP call, the “Use Random SIP/RTP Port” should set to “NO”. Call Hold You can place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button). Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash” button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash. Call Waiting The call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. To toggle between incoming call and current call, you need to press the “flash” button the first call is placed on hold. Press the “flash” button to toggle between the active calls. Call Transfer Blind Transfer Assume that the call is established between phone A and B are in conversation. The phone A wants to blind transfer phone B to phone C: 1. On the phone A presses FLASH to hear the dial tone. 2. The phone A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds) 3. The phone A will hear the dial tone. Then, A can hang up. Note: “Enable Call Feature” must be set to “Yes” in web configuration page.

Then A can hang up to complete transfer. 4. If phone C does not answer the call, phone A can press “flash” to resume call with phone B. Note: When attended transfer fails and A hangs up, the HT81X will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B. 3-Way conferencing The HT81X support Bellcore style 3-way Conference. To perform the 3-way conference, we assume that the call is established between phone A and B are in conversation.Phone A(HT81X) wants to bring third phone C into conference: 1. Phone A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone. 2. Phone A dials C’s number then # (or wait for 4 seconds). 3. If phone C answers the call, then A presses FLASH to bring B, C in the conference. 4. If phone C does not answer the call, phone A can press FLASH back to talk to phone B. 5. If phone A presses FLASH during conference, the phone C will be dropped out. 6.

The following three settings are useful in the STUN Server scenario: 1. STUN Server (under advanced settings webpage) Enter a STUN server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank. 2. Use Random SIP/RTP Ports (under advanced settings webpage) This setting depends on your network settings. Generally, if you have multiple IP devices under the same network, it should be set to Yes. If using a public IP address, set this parameter to No. 3. NAT traversal (under the FXS web page) Set this to Yes when gateway is behind firewall on a private network.

Firmware and Configuration File Prefix and Postfix Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store all of firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus, multiple configuration files for the same device can be stored in one directory.
