Is is possible to prevent SDP re-writes?


I’m using Asterisk to support some SIP development work. Asterisk is re-writing my SDP message bodies, specifically the origin field- I was wondering if it was possible to stop that?

Thanks for any advice,

Asterisk is a back to back user agent, not a proxy.

However, you can, in suitable circumstances, set canreinvite=yes, to make it renogiate the SDP so as to take Asterisk out of the RTP path, although it will still use negotiated codec capabilities.

That makes sense- looks like I chose the wrong pbx. Have got it working on sipxecs instead- thanks for the point in the right direction.
