[Spce-user] Directly Fowarding Calls in sipwise

[Martin Stix]

Hi Andrew!

Last question: Is there a way to disable Comedia in that case because of no NAT in place? Disable it for peerings?

Thanks

Hi Martin,

OK, I see. The Sipwise platform does not generate any SDP on calls or call forwarding, it does that only if you make a call to a conference or voicebox service which is answered by sipwise spce.

The SDP comes from the callee - the Sonus_UAC with first IP octet 185.
Actually it sends the SDP in the 183 which I overlooked before but does not send any in 200 OK. Weird. Anyway, that's callee (Sonus) that sends the a=direction:passive attribute. I think you should check with them..

Hope this helps.
Andrew
