Are you using Nortel Meridian Mail? If that is the case, I think the only thing you can do is use Nortel CallPilot instead. But I don't think that will really be that much better.
If you are using Octel VM and Nortel Meridian PBX with digital intergration, then you can use the Cisco DPA 7610 gateway.
The other thing that can be done is to use Cisco Unity as the only voicemail and use its dual-switch integration. It can be setup to be voicemail for the Nortel PBX users and CallManager at the same time, which makes user migration from legacy to IP much easier. However it still would require a hot-cut of the legacy VM system to the Unity VM system.
