Subject: [OpenSIPS-Users] SDP missing in ACK indialog reinvite only in 1.11.5
SDP in ACK lost in OpenSIPS 1.11.5
This is something that used to work in OpenSIPS 1.8.1, but seems to have been broken 1.11.5.
Using the B2BUA facilities, I make the second leg of the call using b2b_init_request. Then, if required, I move the call to another user agent via a bash shell script, which issues a opensipsctl fifo b2b_bridge.
For this in-dialog reinvite to work, there has to be an SDP in the ACK, which is missing the trace produced using OpenSIPS 1.11.5. It's there in 1.8.1.
Anyway of reintroducing the SDP in the ACK in 1.11.5?
Trace Explanation
-----------------
Objects: 10.10.8.103: source of initial call. Recipipient of reinvite.
10.10.10.205: CentOS running OpenSIPS with B2BUA. In one case, it's CentOS 5.11 running OpenSIPs 1.8.1, the other (broken) is CentOS 6.7 running OpenSIPs 1.11.5.
Call Flow in Trace:

--Invite--> Indialog reinvite, so SDP
<--Trying--
<--200 OK-- With SDP
--ACK --> With SDP in 1.8.1, no SDP in 1.11.5
