Making Phone Calls

Handset, Speaker and Headset Mode

The GXP1610/GXP1615/GXP1620/GXP1625/GXP1628/GXP1630 allows users to switch among handset, speaker or headset when making calls. Press the Hook Switch to switch to handset; press the Headset button to switch to headset; or press the Speaker button to switch to speaker.

SIP Accounts and Lines

GXP1630 supports up to 3 independent SIP accounts, GXP1610/GXP1615/GXP1620/GXP1625/GXP1628 can support up to 2 independent SIP accounts. Each account is capable of independent SIP servers, 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 GXP1610/GXP1615/GXP1620/GXP1625/GXP1628, 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/GXP1615/GXP1620/GXP1625/GXP1628/GXP1630 will flash the other available LINE in red. A line is ACTIVE when it is in use and the corresponding LED is red.

Notes:

  • After entering the number, the phone waits for the No Key Entry Timeout (Default timeout is 4 seconds, configurable via Web GUI) before dialing out. Press SEND or # key to override the No Key Entry Timeout.
  • If digits have been entered after handset is off hook, the SEND key will works as SEND instead of REDIAL.
  • By default, # can be used as SEND to dial the number out. Users could disable it by setting “User # as Dial Key” to “No” from Web GUI🡪Account X🡪Call Settings.
  • For Paging/Intercom, if the SIP Server/PBX supports the feature and has Paging/Intercom feature code set up already, users do not necessarily need toggle to paging mode in the call screen. Simply dial the feature code with extension as a normal call.
  • When dial out via paging, user can see the “call-info” header contains “answer-after=0” and “the “alert-info” header contains “info=alert-autoanswer;delay=0” in the outgoing INVITE.

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:

  1. Press MENU button to bring up main menu.
  2. Select “Direct IP Call” using the navigation arrow keys.
  3. Press MENU to enter the Direct IP Call mode.
  4. Input the 12-digit target IP address (Please see example below).
  5. Press the “More” softkey to make sure the softkey selection “IPv4” or “IPv6” is correctly selected depending on your network environment.
  6. Press “OK” softkey 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/GXP1615/GXP1620/GXP1625/GXP1628/GXP1630 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🡪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 is 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.

Notes:

  • 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 “Use Random Port” to “No” when completing direct IP calls. The option “Use Random Port” is under phone’s Web GUI Settings 🡪 General Settings page.

Shared Call Appearance (SCA)

The GXP1610 / GXP1615 / GXP1620 / GXP1625 / GXP1628 / GXP1630 phone supports shared call appearance by Broadsoft standard. This feature allows members of the SCA group to shared SIP lines and provides status monitoring (idle, active, progressing, hold) of the shared line. When there is an incoming call designated for the SCA group, all of 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.
