I forgot to change the C code bellow to poin to /tmp/hold.wav (see corrected
bellow under //*FIXED label). but you clever coders would have figure it out
anyhow...

Subject: [Freeswitch-dev] uuid_bridge issue
Hi guys,
I've been having a uuid_bridge issue, its very easy to replicate the problem
(sample C module included).
All the C code does is play /tmp/hold.wav file on a loop. I use sofia and a
voip provider , don't know if it has anything to do with it.
All you have to do to make the bug occur is have 3 calls like these and note
the uuids. Then just uuid_bridge any 2. I tried issuing "api break"
commands to stop the music, or park the calls. Same problem. The call
bridge is unusable after the bug occurs.
1) originate sofia/gateway/asterlink.com/12125551234 &stpAgent();
2) originate sofia/gateway/asterlink.com/12125558888 &stpAgent();
3) originate sofia/gateway/asterlink.com/12125559999 &stpAgent();
mod_stpAgent included:
