Comfort noise support

When i am trying to make an outgoing call with the sip provider calling on to my mobile phone i could not deliver the audio voice (ie. my text to speech using swift agi). Gives me this message, If anyone has any thoughts on this, please help me to resolve the same. Works fine when i try with xlite softphone.

NOTICE: rtp.c:787 process_rfc3389: Comfort noise support incomplete in Asterisk (RFC 3389). Please turn off on client if possible. Client IP: 216.168.169.105[/color]

What might be the possible reason i get NOTICE. Appreciate your response.

Thanks.

On the other end is there total silence?

This issue has been sorted out. I am running out with another issue.
I am behind nat. I could establish the call to the required destination but even after the call is picked up the dialstatus is noanswer and the sip provider complains that we are not responding to the 200 ok.

I configured the extenip with my public ip address and when i uncomment the localnet with my ip range and sip reload, the peer becomes unreachable.

Any ideas on this Shadowe.

Hey Naveen, can you duplicate that without being behind NAT? Post config files?
