Hi Colin/Deji

Just thought I should throw this into the mix. I believe this restriction has been lifted with CUE 3.2;

Deji, you are correct on the CUE references. Here is the "old" info;

Cisco Unity Express must be installed on each Cisco CME host router. Cisco Unity Express cannot provide voice-mail services across Cisco CME routers.

Here is the new info (I don't think CUE 3.2 is out quite yet - but soon I hope);

Q. What are the new features introduced with Cisco Unity Express 3.2?

A. Cisco Unity Express 3.2 introduces the following enhancements:

• Integration with multiple Cisco Unified Communications Manager Express sites: Cisco Unity Express (on NME-CUE only) can integrate with up to 10 Cisco Unified Communications Manager Express remote sites. This solution allows centralized voicemail and Automated-Attendant features for up to 10 sites when voicemail at each remote site branch is not essential and there is a small number of users at each site.

Q. Which releases of Cisco Unified Communications Manager Express will be supported with Cisco Unity Express Release 3.2?

A. Cisco Unity Express **will be supported with Cisco Unified Communications Manager Express Releases 4.0, 4.1, 4.2, and 4.3.
