Question : OCS 2007 R2 and Cisco call manager

Dear All,

I have OCS 2007 R2 implemented in my environment; also I have Cisco call manager version 4 implemented.
I want to ask, is there a way to integrate both systems together? Please I need article or link for this

Thanks

Answer : OCS 2007 R2 and Cisco call manager

You don't need a gateway to integrate OCS with CCM.  H.323 is a video codec and SIP isn't even a media codec, it's signaling traffic. I have no idea what that reply is relation to.

To allow Enterprise Voice (VoIP) integrate with OCS 2007 and Cisco Call Manager you can either (a) use a media gateway or (b) configure Direct SIP between OCS and CCM without the need for a media gateway.  Either way the audio calls will be converted to standard G.711 between environements.

Take a look at this blog article for details on Direct SIP integration:
