[Asterisk-Users] catch when no voicemail configured

[Michael George]

I would like to be able to send calls to voicemail() but then catch the 
case where this is no VM configured on the extension and then go back 
to another menu.  However, VoiceMail() will return a -1 and then 
hangup.  I would like to trap it somehow.

Is that possible?
