[asterisk-users] Multiple phones when one is unregistered

[Eric Wieling]

The dialplan below cannot go to voicemail, either something else is 
going on or the dialplan below is not the actual dialplan. Calls only go 
to voicemail when the dialplan runs the VoiceMail application.

Paste the Asterisk console output of a call showing the problem, maybe 
someone can help.
