[Freeswitch-users] sip_unhold_nosdp=true doesn't restore media as per RFC 6337

[Denys Pozniak]

Hello!

As per our investigation, FreeSWITCH (v1.10.2) does not take off the hold
state when receiving SIP INVITE without SDP (RFC 6337).
It answers with 200 OK/SDP with *a=recvonly* (expecting *a=sendrecv* and
taking off from the hold state).
After setting channel variable *sip_unhold_nosdp=true*,  FreeSWITCH starts
sending correct 200 OK/SDP, but it does not restore the media stream
(calling side hears MOH).

How to solve this problem?
