[Asterisk-Users] SIP Disconnect Supervision

[Steve Blair]

Thanks. A couple people suggested looking at voicemail parameters. We 
set some
parameters but I'll double check. The odd thing is that the caller hangs 
up before the
voicemail greeting is played. So in their mind they never attached to 
voicemail. Perhaps
at a protocol level they are attached. I'll run some debugs and see.
