asterisk users - Mar 2006 - Asterisk as Voicemail Server for Option 61c?

Looks like we will be forced to make a move on our voicemail system as
Nortel has declared Meridian Mail an end of life product.  Frustrating
thing is that it would seem their only reason for it is so they can
force our hand to move to Call Pilot.

Is there any documentation and feedback out there of how people have
used Asterisk as a voicemail system for a legacy PBX?  We've got about
800-1000 boxes at any point in time. Would be a nice bonus to provide
unified messaging as well.

Thanks,
Jeremy

I could not get our Nortel Norstar to interface with Asterisk over T1.
The outbound DTMF tones weren't being recognized by Asterisk unless you
dialed really, really fast.  It was weird.  I still have it and could
test further if necessary.

I decided that for my organization it would be just as easy to forklift
the old thing as to continue to mess with the integration.  Plus there
would be other advantages.

We have set it up on an 81C and an 11C using PRI as the interface.  The
only issue we've run into is that the 81C shows the full 10-digit caller
ID value instead of the 4-digit extension.  We don't have that issue on
the 11C for some reason.  It may have to do with having networking
enabled (so we can force unique caller ID values down the central office
PRI lines).

Take a look at the directions in asterisk-meridian-a1.pdf (linked at
http://www.voip-info.org/wiki/view/Asterisk+legacy+integration).  That
should give you a good head start.

We used a TE110P card in the * system and found that, for whatever
reason, if you need to take down the line between * and the Meridian,
you need to leave the line down for 45s - 1 minute.  If you don't, the
channels will come up in MBSY or FE MBSY and stay that way.  I don't
know why, but it is very consistent on our system.

Thanks,
Greg
