Can't hear TCL IVR from remote

Unanswered Question
Mar 3rd, 2007


I'am calling with a SIP softphone into my CME B-ACD number, from a remote location some 320 ms RTT away. I can at times hear bits of the messages but in general is only silence. Call to PSTN or via ITSP are OK.

I'm a bit surpised, looks like when the media is generated by a codec is ok, but audio files are not.

What could be the cause ?

I have this problem too.

Which codec is configured to speak CME B-ACD to your SIP Phone.

Have already hardcode to G711u ?

Yes, g711u harcoded.

I took some RTP traces and noted that SSRC changes continuously, that does not happen during a successful call.

Assuming an RTP problem, how can I further debug RTP ?
