To enable g729 codec you will need to configure using Telnet and go into the ST780-WL advanced configuration.

First, configure the Telephony ports (through the webbrowser) with your 7xxxxx account and the sip.gismotel.com SIP proxy as decribed in the registration email and at our general settings on the main support page at the website.

Then, open a Command Prompt / Dos Box and follow the instructions below:

Open Dos box

telnet 192.168.1.254

at the Prompt:

{Administrator}=>voice

{Administrator}[voice codec]=>help
Following commands are available:

--> Now type list
