Hello,
I'm going to send 183 w/o sdp stimulating Cisco to send PRACK. After
rebilding INVITE and sending it to callee we are expecting normal call
flow: 183/180 (from callee) and 200 (or whatever final).
Thanks.

Hello,
saving an invite for later use can be achieved with
t_suspend()/t_continue -- see the tmx module.
However, regarding what you need, how do you plan to generate the sdp
for early media/183? You need ip, port and media description, are they
going to be just some random/invalid values?
Cheers,
Daniel
