Unity and Corp Domain

upgrading Unity 2.46 to 3.x <br>(little bit of Callmanager [3.12C] too)<br><br>Callmanagers are in own workgroup (2 - pub and sub)<br>Unity in it's own domain w/ RT ver Exch 5.5 on the Unity box (voicemail only for now)<br>corp Lan in it's own domain <br>(CCM & Unity in 10 network, while corp Lan in 172 network)<br><br>would like to keep the VoIP separated from corp domain,<br>do you see a problem with having the CCM join the Unity domain. <br>(have experimented a little in lab enviro and haven't seen any problems yet !!! )<br><br>Then later when the corporate Exchange 5.5 is upgraded to E2K enterprise (possibly clustered), then can point Unity to corporate Exchange for unified messaging. Still keeping the domains separated. <br><br>there will be a cat6509 doing the switching <br><br>one reason for CCMs joining the unity domain is that HIDS will be installed on the VoIP - each CCM and Unity will run an agent (recommended to be either w/g or domain not both?) <br><br>thanks<br><br>

Re: Unity and Corp Domain

Assuming that your VOIP domain and Corp domain are in different AD forests you are going to run into a snag when you try to connect Unity 3.X to the Exchange 2000 cluster. Windows 2000 does not support forest to forest trusts. Check out:

I would suggest not trying to disjoint your converged network. Our biggest enterprise customers run Unity is the same domain. It's not really different that other member servers.
