I would like to know if it`s possible to integrate a UC500 with a MOC (Microsoft Office Communicator), if it`s so, where can i find information about it?

Thanks in advanced

I have this problem too.

Hi Manuel,

CME doesn't officially support third party SIP phones.

This is the minimum require configuration for SIP CME if you want to try it:

voice service voip


registrar server

voice register global

mode cme

source-address port 5060

max-dn X

max-pool X

voice register dn 1

number 1000

voice register pool 1


type ! If it's 3rd party, omit this

number 1 dn 1

username X password X ! Required if IP phone's address is on different subnet than SIP CME source address

Most SIP phones will register with SIP CME, yes. It just isn't officially supported, but the CME should be fully RFC compliant.

Hi Nick,

Along the same vein - or perhaps what the original poster meant. I am interested in integrating CME (UC500- and 2800-based) into the Office Communicator client. Specific interests include click-to-call from the Communicator client.

Is this possible?

Thanks in advance,

Hi Marino,

The MOC is a SIP based solution. Unless the MOC can simulate a gateway instead of client, this would need to be registered via SIP CME. Most SIP compliant devices seem to register fine to SIP CME, but it wouldn't be a TAC supportable solution.
