[Freeswitch-users] Hold is broken in trunk 16055

[Lei Tang]

Hi Anthony and Brian, I have grep some sip trace log, Could you please take
a look at the attachments? lega.pcap is the log of a leg, legb.pcap is the
log of b leg. It seems fs never sent the reinvite request to b, and sent
200ok response without sdp content to a immediately.
My scenario is as follow, and I'm using proxy media mode.

       invite  <bridge>  invite
a <------------> FS<---------------> b
