TELEPHONY FEATURES

Make Phone Calls

Handset, Speaker, and Headset Mode

The GRP261X/GRP2624/GRP2634/GRP2670/GRP2650 allows users to switch between handset, speaker, or headset when making calls. Press the Hook Switch to switch to the handset; press the Headset button to switch to the headset, or press the Speaker button to switch to the speaker.

Multiple SIP Accounts and Lines

GRP2612/GRP2612P/GRP2612W/GRP2612G support up to 2 SIP accounts with 4 line keys; GRP2613 supports up to 3 SIP accounts with 6 line keys and GRP2614 supports up to 4 SIP accounts with 4 line keys. GRP2615 supports up to 5 SIP accounts with 10 line keys. GRP2616 supports up to 6 SIP accounts with 6 line keys, GRP2624/GRP2634 supports 4 accounts and 8 lines, GRP2670 supports 6 SIP accounts with 12 lines and GRP2650 supports 6 SIP accounts with 14 lines. 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 the 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 GRP261X/GRP2624/GRP2634/GRP2670/GRP2650, 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

Support added for disabling the feature of selecting an account from LCD.

  • For Paging/Intercom, if the SIP Server/PBX supports the feature and has the Paging/Intercom feature code set up already, users do not necessarily need to switch to paging mode on the call screen. Simply dial the feature code with extension as a normal call.
  • When a call is dialed out via paging, users 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.

  • It is possible to mute the call at the dialing stage by composing a number, dialing the call, and pressing the mute button before the call is answered.

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. When the phone is at an idle state, press any number key or * key to bring up “On-hook Dialing” page;
  2. Press round MENU key or “DirectIP” softkey
  3. Input the target IP address (Please see the example below);
  4. Press the “Dial” softkey to dial.
Note

When completing direct IP call, “Use Random Port” option should be set to “No”.

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 (.), and the # key represents the colon (:).

When only dialing the IP address (example: 192*168*1*60) the call will automatically go through the default port 5060.

Figure 22: Direct IP Call
