[asterisk-users] Mysterious dropped calls

[Mark Rosedale]

So I'm now using asterisk 1.8.5rc1 for Asterisk. I'm still getting mysterious dropped calls. This only happens on calls that are outbound on Dahdi and mostly happens in conference calls particularly 8xx-xxx-xxxx

This is the output of the hangup.
