Is it possible to run Nortel VOIP Phones on CUCM?

[Paul Hathaway]

Hi

One of the my Companies Sites over in Ireland has a Nortel Phone System which they are looking to upgrade to VOIP, and there is a Cisco Call Manager Cluster version 4.2 in the UK.

I'm wondering if its possible to Integrate the 2 in some way by either haviing Nortel VOIP Phones running on the CUCM over a Global WAN Link , or an a Local Voice Gateway?

Thanks

I think the easiest solution is to use H.323 trunk. See if the following helps.
