Summary:                    Combination dtmfmode=info, directmedia=yes/update
and transfers blocks Asterisk.
Description: 
When we use as dtmfmode INFO and PtP audio (directmedia=yes or update), and
we  do an attended transfer Asterisk blocks (no Segfault).

We attach "core show locks" command output and some info from gdb.
Asterisk is compiled with "DON'T OPTIMIZE" and "DEBUG THREADS" flags.

To reproduce it, we make a call A->B and A does an attended transfer to C,
but also occurs with transfers like A->B and B transfers C.


Thanks.

Sometimes we receive this warning:
[Feb  3 10:16:08] WARNING[18810]: rtp_engine.c:1209 remote_bridge_loop:
Channel 'SIP/100-00000006<ZOMBIE>' failed to break RTP bridge

But in this case Asterisk doesn't block. :(
