Hi All,
I'm looking for advice/opinions on a UC solution I am proposing for an upgrade/refresh of an existing environment.
Currently:
This is a centralized multi-site deployment located in one data center. There are approximately 700 registered endpoints.
The requirements for the upgrade were left general enough:
The data centers are connected via 100Mbps connection over QoS enabled link. The RTT between dc's is approx 45ms.
Proposed solution:
A rebuild from scratch approach is accepted as the current implementation is somewhat of a mess.
Questions:
What is the feel for CUCM 8.0 in regards to bugs in a .0 release? Am I safer to go with 7.1.5? There are no features in 8.0 that are currently needed.
Clustering over WAN...given that the DC's are connected by a solid 100Mbps QoS pipe, should I have any concerns with this design for CUCM, CCX and CUC?
General opinions/comments on major gotcha's to look out for?
Any and all advice/comments is very much appreciated!!

UCM 8 has thus far proven stable where I am using it. If you want to use the 7.1 train instead you should choose the latest 7.1(3) build. The 7.1(5) version can not be upgraded until the 8.5 release.

You should be fine; just be sure to mark the intra-cluster signaling traffic properly to guarantee it the necessary bandwidth for proper replication.
