Hi Martin,

It is possible to use OpenSER + RTProxy as a small Session Border Controller. However, the RTP Proxy does _not_ signal to the SIP Proxy, if a RTP Session timeouts. On RTP Session timeout, the RTP Proxy will clean up the session by itself.

There's no mechanism in OpenSER to terminate a call. There is a patch in the tracker that will add this ability to OpenSER. You can use the sst module to enforce periodic reINVITES between the two parties.

I want to pass ALL calls to an extra OpenSER+RTPProxy, so ALL calls use RTP Sessions via RTPProxy. Can the RTP Proxy signal to the SIP Proxy, if a RTP Session timeouts, so the SIP Proxy can signal a BYE to both legs of the call?

I need something like this, to not account timeouted calls. For example broken calls, which never end.

any other ideas? professional session border controllers are very very very expensive.
