[cisco-voip] 1 Unity Connection with 2 CM clusters

[Sandy Lee]

I have an ICT between the 2 clusters, but it's not a QSIG one. I will try it with this protocol on.

Thanks.

Sandy.

You can either use a dual integration (if UC can do this) or set up a qsig tunneled ICT between the two CUCM clusters.  Have a route pattern pointing to that trunk for the numbers that exist on the other cluster and MWIs will be passed between.

Hi,

We're migrating from CUCM 4.1(3) to UCM 7.1(3) with a new server migration approach. We have a Unity Connection 7.1(3) that is already SCCP integrated with the CUCM 4.1(3).

My question is how do I deal with my 4.1(3) cluster for the MWIs to continue working? In the lab, I configured the SIP integration for the UCM 7.1(3) and it worked just fine, but MWIs stopped working for the 4.1(3) guys.

In the doc, it says that I need to do a translation pattern, but there's no example. Did anyone of you went through this and could give me an example?

Any help would be appreciated.

Thanks and regards.

Sandy.
