Hi, Xaled!
No, there should bot be an SDP, because you don't have an SDP (the media
server is gone, and you don't know the callee's SDP). Instead, the
module is doing a late negotiation to find out advertised caller's SDP,
and present it to the new callee.

Subject: [OpenSIPS-Users] OpenSIPS 3.2 B2B tutorial pre-paid example
Hi,
I tested the 3.2 Prepaid example from B2B tutorial
https://www.opensips.org/Documentation/Tutorials-B2BUA-3-2
In Scenario Schema there is a first reinvite from OpenSIPS B2B to caller - this
reINVITE in my tests comes without SDP. Should not there be an SDP, or am I
missing something in this scenario?
