3. Press OK to select
4. Input the 12-digit target IP address. (Please see example below)
5. Press OK key to initiate call
To make a quick IP call, please see next section.
For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input
the following: 192*168*1*60#5062 - The “ * ” key represent the dot“.” ; The “#” key represent colon :”. Press
OK to dial out.
Quick IP Call Mode
The GXP21xx 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-number. This is possible only if both phones are in
under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP server.
Controlled static IP usage is recommended.
Setting up the phone to make Quick IP calls
To enable Quick IP calls, the phone has to be setup first. This is done through the web-setup function. In the
“Advanced Settings” page, set the "Use Quick IP-call mode to YES. When #xxx is dialed, where x is 0-9 and
xxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. “aaa.bbb.ccc” is from the local IP address
regardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but OK).
For example:
192.168.0.2 calling 192.168.0.3 -- offhook the phone, dial #3 followed by SEND or #
192.168.0.2 calling 192.168.0.23 -- offhook the phone, dial #23 followed by SEND or #
192.168.0.2 calling 192.168.0.123 -- offhook the phone, dial #123 followed by SEND or #
192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3
NOTE:
If you have a SIP Server configured, a Direct IP-IP still works. If you are using STUN, the Direct IP-IP
call will also use STUN. Configure the “Use Random Port” to “NO” when completing Direct IP calls.
ANSWERING PHONE CALLS
Receiving Calls
1. Incoming single call: Phone rings with selected ring-tone. The corresponding account LINE flashes
red. Answer call by taking Handset/SPEAKER/Headset off hook or pressing SPEAKER or by
pressing the corresponding account LINE button.
2. Incoming multiple calls: When another call comes in while having an active call, the phone will
produce a Call Waiting tone (stutter tone). Next available lines will flash red (as described in section
4.3.2). Answer the incoming call by pressing its corresponding LINE button. The current active call
will be put on hold.
3. Paging/Intercom Enabled: Phone beeps once and automatically establishes the call via SPEAKER.
(PBX or Server must also supports this feature)
