trunk-sip with the provider failure

can any one help me

Hi,

You are too short in asking question :)

Seems issue with codec. Check with your provider which all codecs are supported and configure gateway accordingly. If you are not sure, try to send all codecs (whatever possible) and see if it makes any change.

Hi,

Configure voice-class codec with at least G711u, G711a and G729, and assign it to outbound dial peer. Then make test call and share the output of debug ccsip messages and debug voice ccapi inout.
