Grandstream Networks GXP1400, GXP1405 user manual Making Calls using IP Addresses, For example

•Dial the number to Page/Intercom

•Press “SEND” button to dial out

NOTE:

•Dial-tone and dialed number display occurs after the handset is off-hook, or handset button is pressed, or speaker button is pressed, or the line key is selected. After dialing the number, the phone waits 4 seconds (by default; No key Entry Timeout) before sending and initiating the call. Press “#” button to override the 4 second delay.

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 a 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 these steps:

•Press MENU button to bring up MAIN MENU

•Select “Direct IP Call” using the arrow-keys

•Press OK to select

•Input the 12-digit target IP address. (Please see example below)

•Press OK key to initiate call.

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 represents the dot “.”; the “#” key represents colon “:”. Press OK to dial out.

The GXP1400/1405 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.

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 -- dial #3 followed by # 192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # 192.168.0.2 calling 192.168.0.123 -- dial #123 followed by #

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.
