[OpenSIPS-Users] One Way Audio

[Ross Beer]

It looks like it is sending in to the server's IP address and back to it's self which is strange.

 

I think this has something to do with the SDP and possibly my router. I am doing an echo test so audio should come back, however Asterisk should stay in the media path as it does when directly using asterisk.

 

If I use a different network there isn't a problem however directly using asterisk on the problem network has no issues.

 

Ideally I would like to resolve this issue so all networks can use OpenSips.

 

I am currently testing MediaProxy however it does not appear to receive the RTP stream from the soft phone either.

 

Thank you for you help,

 

Ross

In the wireshark trace what IP is the softphone sending the RTP packets to? Whats the destination? Is it actually sending the RTP to the Asterisk box?
