[cisco-voip] Cisco & Avaya integration

[Nick Marus]

I work for a company that deploys both avaya and cisco voip and we
have been asked to similar stuff. I have done the opposite, that is
getting a cisco phone with a sip image working on an avaya. For what
you want, as far as i know, this would require the Avaya phones to be
running the avaya sip image and you would need cm5 for sip phone set
support. I am wanting to lab up something similar myself using the
4610/4620's. The 4606 is an older avaya phone and may not support sip,
and I dont think it is being sold anymore. I cant recall tho.

For #2, Cisco Phones use tftp just as avaya does. the server can be
anything that can do host tftp. Avaya's files are slightly differnt in
format, but essentially the same. A config file and a firmware load.
Avaya does require differnt dhcp options to tell the phone where the
tftp server is tho. Cisco =150, avaya is 176 and uses a string that
includes several required options.

Everything between avaya and Cisco can integrate (both directions) if
you use h323 on your cisco gateways. i have a callmanager that gets
trunks directly from an avaya s8700 with no external cisco gateway and
I have worked on some other sites that have avaya trunking to a cisco
h323 gateway.
