This is what I have:

_3XXX,1,Dial(SIP/${EXTEN})
_3XXX,2,Voicemail(${EXTEN})
_3XXX,3,Hangup
_3XXX,102,Voicemail(${EXTEN})
_3XXX,103,Playback(invalid)
_3XXX,104,Hangup

SIP client is called. If it is not logged in, calls it's voicemail. If
voicemail doesn't exist, plays back invalid.

If SIP client is busy, goes to voicemail as well.
