It's not SIP, currently, well over a year ago Avaya demonstrated SIP
functionality in both the phones and in their Multivantage PBX software.
This has not been released, apparently due to lack of business demand...
I've tried making one work as is with asterisk and a number of other
h323 products, however, I've not yet had any success... Avaya seem to
have really filled these with lots of proprietary hacks...

You would not be able to get a SIP phone talking to the Avaya PBX for
the reasons mentioned above... You could possibly get an h323 trunk
between the * and the Avaya PBX, but, I have not tried this yet so this
too may not work... Also, something worth mentioning, the number of IP
trunks you can have is limited by the number the Avaya PBX is licenced
to use... If your company is not currently using trunks, there may not
be any trunks available to use...

Not a lot of good news there, but I hope it's helpful to you...
