Hi, in order to try managing NAT when the SDP negoziation is done via "200 OK" - "ACK" (instead of "INVITE - "200 OK") I need a UAC that can send INVITE with empty SDP in order to force the called to generate the SDP offer in the reply.
Is there any UAC allowing it?
Thanks a lot.
Hi,
I am simulating this with sipsak, seems to do the job...

Can't you perform some sort of mangling in OpenSER to rip the SDP out?

Hi,
afaik there is no "remove_sdp()" available, so its a painfully manual work with textops functions....and you also need to correct the header manually.
maybe someone knows something better ;)
cheers.

But then the caller will receive a SDP offer when he expects to receive a SDP reply.
not if you do the mangling on another opener/host before it reaches the correct one :-)
cheers.
