[Freeswitch-users] Some problems with bypass-media

[Neven Boric]

Ok, I tried with master, and something strange happened. I'm pretty sure it
worked last night, but now I'm testing again and I'm getting the same
behavior I described with 1.4. I don't even have to get a third phone
involved. All I do is call from A to B, put B on hold and then wait, and
about ten seconds later, FS will hangup both calls, as if some timeout was
triggered. I get the same error on the log:

140 at 10.50.100.16:5060 reading on a session with no media!

I also get no MOH on the phone that was put on hold.
