[Asterisk-Users] Voicemail issue

[terry at localhost.otherwiseguy.com]

Ok, the first set of extensions is hit via
PSTN->Asterisk2->IAX->Asterisk1.  The second is dialed via a SIP phone
registerd with Asterisk1.

#extensions.conf for Asterisk1
[test]
exten => _5555551212,1,Dial(SIP/6711,20,tr)
exten => _5555551212,2,Voicemail2(u6711 at company)
exten => _5555551212,3,Hangup

exten => _6711,1,Dial(SIP/6711,20,tr)
exten => _6711,2,Voicemail2(u6711 at company)
exten => _6711,3,Hangup

#extensions.conf for Asterisk2
[incoming]
exten => _5555551212,1,Dial(IAX2/asterisk2 at asterisk1/5555551212 at test)

I get to voicemail either way.  It just doesn't playback the unavail on
the IAX call.  Plays back fine on the SIP call.  Both calls show up as
playing voicemail/company/6711/unavail on the console.  I noticed this
first on a much more complicated setup with macros, etc.  But recreated it
all statically as above just to test the problem (and it was still a
problem).  Anyone have any clues?
