Making Phone Calls

Handset, Speaker and Headset Mode

The GXP1760/GXP1760W/GXP1780/GXP1782 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.

Multiple SIP Accounts and Lines

GXP1760W can support up to 3 independent SIP accounts, GXP1780/GXP1782 can support up to 4 independent SIP accounts. Each account is capable of independent SIP server, user, and NAT settings. Each of the line buttons 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.

To toggle between SIP accounts when the line is off-hook, keep pressing the line key until the desired account show up.

For example: If 2 independent accounts are registered on GXP1760W/GXP1780/GXP1782, 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 phone will flash the other available LINE in red. A line is ACTIVE when it is in use and the corresponding LED is red.

Note: Regularly, to make another call under normal Line mode, users can press another line to access new call screen and initiate the outgoing calls. However, when enabling Account Mode under web GUI 🡪 Settings 🡪 Programmable Keys Settings 🡪 Call Screen Settings, a softkey “New Call” will be displayed to get another line for initiating calls on the same account with the same line key button, so lines will be grouped by account. Users can switch between lines by pressing on “Swap softkey or navigate between lines using the up/down arrow keys.

  • 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.

During an active call, user can see call info on LCD such as: the call lasting time, contact information if the number already be saved in phonebook. When dialing DTMF, user can press round OK button to switch to call info page.

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:

  • Press MENU button to bring up main menu.
  • Select “Direct IP Call” using the navigation arrow keys.
  • Press MENU to enter the Direct IP Call mode.
  • Input the 12-digit target IP address (Please see example below).
  • Press the “More” softkey to make sure the softkey selection “IPv4” or “IPv6” is correctly selected depending on your network environment.
  • 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 (:).

Quick IP Call Mode:

The GXP17xx 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 apply 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 “User Random Port” to “No” when completing direct IP calls.

Answering Phone Calls

Receiving Calls

Shared Call Appearance (SCA)

The GXP1760/GXP1760W/GXP1780/GXP1782 phone supports shared call appearance by Broadsoft standard. This feature allows members of the SCA group to share 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.
