Unity Voicemail and Existing AD/Exchange 2000 coexistence

Can a Unity Voicemail server be installed into an Active Directory Domain that already has Exchange 2000 email installed.

I do see that a UnityVM server can be installed into an W2K AD Domain but am unsure as to how Unity VM would coexist with an existing Ex2k email environment.



Windows 2000, Message Store, and Network Requirements

Requirements for Cisco Unity Voice Messaging

The Cisco Unity system may or may not have a network connection.

Windows 2000 domain

requirements The Cisco Unity server is a domain controller/global catalog server in its own domain or a member server in an existing Windows 2000 or Windows NT domain.

Message store requirements Domino is not supported.

For Cisco Unity with Exchange—Exchange may be installed either on the Cisco Unity server or on a separate server. See also Table 1, "Supported Message Store Versions for Cisco Unity Voice Messaging." You do not need to purchase Client Access Licenses (CALs).

Network requirements With a network connection, minimum 10 Mbps with minimal network access, if any.

For Cisco Unity with Exchange—If Cisco Unity failover is configured, recommended 100 Mbps connection between the primary and secondary servers.


Re: Unity Voicemail and Existing AD/Exchange 2000 coexistence

It would work similar it UM except each user would have an email mailbox and a voicemail mailbox. That really is the only difference.

The Unity server could have Exchange installed 'on box' but it doesn't need to. If Exchange is installed on box it should only have voicemail mailboxes, no email mailboxes. Also, you wouldn't want to have Unity be a DC/GC because it would process non-voicemail related client logons, etc.

Hope this helps...
