[asterisk-users] Voicemail from sip phones

[astuser at braingia.org]

Hello,

I'm having a problem in voicemail check attempts from SIP-based phones.  I've searched
a ton of docs but don't see anyone else having a similar issue.  I have a TDM22B with
two non-sip phones connected to it as well as several SIP phones including a GXP-2000
and some X-Lites.  Users of the real phones in the same context can pick up and dial
*8 to get to VoiceMailMain() just fine.  However, SIP users cannot.  When they dial *8
a message comes on stating "The person you are calling is unavailable."

I can get the MWIs to light up on the SIP phones when there's a voicemail waiting 
but there's no way to check it.  SIP debugging through the CLI hasn't so far given any 
great hints.

I've tried various settings of mailbox= and vmexten= combinations in the sip.conf. 
For someone with a mailbox of 126 at default and extension of 126 in the 'internal'
context, what should the vmexten be?  The real phones and the sip phones are all
within the same 'internal' context in extensions.conf, as is the *8,1,VoiceMailMain()
function call.

Any hints or suggestions would be appreciated.

Here's a sample of one of the Xlite SIP configurations that isn't working:

[user]
type=friend
regexten=126
secret=greatsecret
qualify=200
host=dynamic
canreinvite=no
context=internal
mailbox=126 at default
vmexten=126
