    FS-9854: [mod_sofia] SDP O/A fails to put sdp in messages after certain kinds of sip traffic

    FS-9829 #resolve [FreeSWITCH 200ok to second reINVITE on a dialog doesn't contain an SDP.]

I think this specific issue is in the 3387b90 commit, but the other commit is similar scenarios that will cause the same sort of issue

I do plan on working on backporting both of these to the v1.6 branch for the next release, but have not completed that yet.

Hello,

I have tested with master branch and I verified that I don't have this issue.

This issue will be solved at stable version?

What it is the commit id that solves this issue?

Thanks in advance.

Hello,

I have a FreeSwitch with vanilla configuration connected to an SIP Provider.
I configured the proxy-hold=true configuration on Sofia Internal profile so when i activate the Hold on internal sip regs, it will be forwarded to SIP Provider.

The SIP Provider provides MoH when requested.

I have a problem that results on the call on silent or terminated by SIP Provider when I do the next actions: 
1- I receive a call from the SIP Provider
2- the caller activate MoH and deactivate MoH
3- the callee activate the MoH
4- Now the call is silent (with other SIP Provider the call is dropped by SIP Provider)

I notice that on step 3, the FreeSwitch send a Re-INVITE without SDP, so I think this causes the call to be silent, or sometimes the SIP Provider drop the call.

I replicate this issue creating a sipp scenario and verified this issue.

SIPP scenario to replicate this issue

Freeswitch logs:

Command to use sipp scenario
sipp  -i 172.21.0.1 172.21.0.11:5080 -s 1001 -sf scenario.xml -m 1 -l 1 -r 1 -rp 1000

#172.21.0.1 -> local ip
#172.21.0.11 -> Freeswitch IP



Best regards,
Jose Lopes
