I have an IP Telephony setup with 3 CME in differnt location with 3 CUE which currently running.Now client has planning for an upgrade for Multi site with centralized call processing deployment model.
That means one CME will convert to CUCM, and will keep the the other 2 CME as SRST Gateway.So there will be one CUCM + Gateway in HQ and other 2 sites will be SRST Gateway.
My doubt is
1. How I can convert the CUE License in each locations from CME to CUCM.What is the configuration for converting this?.Do I need erase the configuration for AA and Voice mails for the CUE in each location and start as s fresh installation ?
2. )Is it possible to use 3 CUE (2 of them are over the wan) with one CUCM?if Yes..How?
You need to change the license running on the CUE to the CCM license. This will allow the CTI ports on CUCM to register with the CUE IP address. (e.g. cue-vm-license_250mbx_ccm_7.0.6.pkg)
Install the ccm license using ftp, and reload the CUE module.
Then run the show ccn status ccm-manager and show call-agent.
The call-agent should now be changed to CCM.
Remember that you'll need to configure jtapi subsystem and triggers as well corresponding to the CTI ports on CUCM.
Yes you can use the 3 CUE with CUCM. Just configure a different VM pilot number, and different set of CTI ports for each of them. Then assign the respective VM profile to the sets of phones belonging to the corresponding branch.
