UC540 - SIP Trunk YX Wireless

[silvia.candela]

Hi,

I´m trying to configure an YX Wireless as a SIP Trunk for the UC540. I can receive calls, but i can´t make any call, maybe someone who has already configure this can give some advice.

Any help will be appreciate.

Thanks.

I think the problem is the codec. I've configured the SIP Trunk to use the codec G711ulaw, but checking the logs the outgoing calls use the codec g729r8 which is not supported by the gateway. Can someone help me change this??

Is it possible via CCA or do I have to use the CLI??

Hi Silva,

You might want to try upgrading your version of CCA. The missing voice-class codec commands have been fixed in the latest version I think.
