Hi Team

I think, I might have found something that was overseen in the rtpengine module.

A (ipv6) <=> rtpengine <=> B (ipv4)

Invite+SDP from B to A

It looks like this works as expected. A SDP c= line is created containing an ipv6 address.

Invite, no SDP from A to B Reply with SDP offer from B to A

The information about A being reachable via ipv6 and therefore an ipv6 c= line being required, could be taken from the via header of the reply. But am I right to fear, that the rtpengine module does not do this at the moment?

Mit freundlichen Grüssen
