Hi Roy,

Jim Van Meggelen, a TAUG member and co-author of "Asterisk, The Future of
Telephony" did a presentation on that topic over a year ago.  I think that
was our first PodCast.  You should be able to find a link to it on the
taug.ca website.  Jim's company does this stuff routinely.

I'm not sure how big your system is or what the details are, but always felt
like you had to have some pretty specific needs to justify fully integrating
Asterisk with an old Nortel box.  I've done half measures before.  What I
have done in cases where PRIs is used, is put the Asterisk box inline with
the PRI so that the Nortel box doesn't know the difference but I can still
dial between them and out to the PSTN.  IE  Bell  <--> PRI <--> Nortel

In an Avaya environment I put the Asterisk box on a lineside PRI but I
wasn't really using it as a PBX as much as an IVR.  It worked nicely though.

Once I have the systems tied together, I've migrated one or two
departments.  I moved IT because they give good feedback and you can tell
them to suck it up if somethings not quite perfect yet.  Another thought is
to pick a non-critical, non-technical department because it's nice to get
feedback from non-geeks.

I hope this helps,
Dave

 G'day,

I have been working with our Asterisk system for a while
now and getting close to final stages. I hate the thought
of just pushing all the users over to a new system over night
and hoping for the best ;)

Anyone seen any integration between the old Nortel stuff and
Asterisk (hardware/software) ? My current plan just uses a box
that converts my existing Meridian phones to SIP.

Thanks in advance for any advice.
Roy
