SIP ACCOUNTS AND LINES
GXP1620/GXP1625 can support up to 2 independent SIP accounts; and GXP1610 can support 1 SIP
account. Each account is capable of independent SIP server, user and NAT settings. Each of the LINE
button is "virtually" mapped to an individual SIP account. In off hook state, select an idle line and the dial
tone will be heard.
To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. The
user can switch lines before dialing any number by pressing the LINE buttons.
For example: If 2 independent accounts are registered on GXP1620/GXP1625, when LINE 1 is pressed,
the LINE 1 LED will light up in green. If LINE 2 is pressed, the LINE 2 LED will light up in green and the
subsequent call will be made through SIP account 2.
Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the
"virtually" mapped line is in use, the GXP1610/GXP1620/GXP1625 will flash the other available LINE in
red. A line is ACTIVE when it is in use and the corresponding LED is red.

MAKING CALLS USING IP ADDRESSES
Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP proxy. VoIP calls
can be made between two phones if:

Both phones have public IP addresses; or

Both phones are on the same LAN/VPN using private or public IP addresses; or

Both phones can be connected through a router using public or private IP addresses (with necessary
port forwarding or DMZ).
To make a direct IP call, please follow the steps below:
Firmware Version 1.0.0.11
GXP1610/GXP1620/GXP1625 User
Guide
Page 20 of 31

When phone is at idle state, press any number key or * key to bring up “Onhook Dialing” page;

Press round menu key or "DirectIP" soft key;

Input the target IP address (Please see example below) ;

Press "OK" soft key to dial.
For example:
If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following:
192*168*1*60#5062. The * key represents the dot (.), the # key represents colon (:). Wait for about 4
seconds and the phone will initiate the call.
Quick IP Call Mode:
The GXP1610/GXP1620/GXP1625 also supports Quick IP Call mode. This enables the phone to make
direct IP calls using only the last few digits (last octet) of the target phone's IP address. This is possible
only if both phones are under the same LAN/VPN. This simulates a PBX function using the CSMA/CD
without a SIP server. Controlled static IP usage is recommended.
To enable Quick IP Call Mode, go to phone's Web GUI->Advanced Settings->Call Features, set "Use
Quick IP - call mode" to "Yes". Clicking on "Save and Apply" on the bottom of Web GUI page to take the
change. To make Quick IP Call, take the phone off hook first. Then dial #xxx where x is 0-9 and xxx<255.
Press # or SEND and a direct IP call to aaa.bbb.ccc.XXX will be completed. "aaa.bbb.ccc" is from the
local IP address regardless of subnet mask. The number #xx or #x are also valid. The leading 0 is not
required (but it's OK).
For example:

192.168.0.2 calling 192.168.0.3 -- dial #3 followed by # or "SEND";

192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # "SEND";

192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # "SEND";

192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3.
Note:

The # will represent colon ":" in direct IP call rather than SEND key as in normal phone call;

If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will
also use STUN;

Configure the "User Random Port" to "No" when completing direct IP calls.

SHARED CALL APPEARANCE (SCA)
The GXP1610/GXP1620/GXP1625 phone supports shared call appearance by Broadsoft standard. This

progressing, hold) of the shared line. When there is an incoming call designated for the SCA group, all of
Firmware Version 1.0.0.11
GXP1610/GXP1620/GXP1625 User
Guide
Page 26 of 31
the members of the group will be notified of an incoming call and will be able to answer the call from the
phone with the SCA extension registered.
All the users that belong to the same SCA group will be notified by visual indicator when a user seizes the
line and places an outgoing call, and all the users of this group will not be able to seize the line until the
line goes back to an idle state or when the call is placed on hold (with the exception of when multiple call
appearances are enabled on the server side).
In the middle of the conversation, there are two types of hold: Public Hold and Private Hold. When a
member of the group places the call on public hold, the other users of the SCA group will be notified of
this by the red-flashing button and they will be able to resume the call from their phone by pressing the
line button. However, if this call is placed on private-hold, no other member of the SCA group will be able
to resume that call.
To enable shared call appearance, the user would need to register the shared line account on the phone.
In addition, they would need to navigate to "Settings"->"Programmable Keys" on the Web UI and set the
line key mode as "Shared Line". If the user requires more shared call appearances, the user can
configure multiple line buttons to be "shared line" buttons associated with the account.
