using microsoft ocs with cisco 3745 and trunk gateway
I have been assigned to implement our gateway solutions. We are presently using microsoft ocs, am planning to connect nm-hdv-2e1/t1 gateway to the router and to pstn. Any idea on whether the microsoft ocs can work with the gateway?
Re: using microsoft ocs with cisco 3745 and trunk gateway
I dont think the 3745 will support a SIP trunk from anything. only MGCP, H323, etc. OCS only uses SIP or if you have a T1 card in the server, then it will connect via T1 (server) to T1 (router).
If I recall, MSFT is not supporting the Cisco Router yet for OCS - SIP - Cisco Router. They are only using SIP gateways from Intel, AudioCodes, NetCom, etc. They have an approved list there.
The other way you can do this, which I have set up is to use Presence. You can setup a OCS-SIP Trunk ---> Presence. Presence is connected to CallManager which processes the calls in/out.
Remember the koolaid MSFT is pushing out about OCS is only koolaid, dont buy into. It's not a PBX or call processing platform. It's a SIP endpoint to make and take calls, anything else it cant handle. (911, MWIs, call processing, etc)
Sorry, not a huge fan of the OCS as a PBX. The IM product is great. If MSFT and Cisco can get the call control piece to work in the SIP trunk, the IM client and CallManager/Presence will be great for everyone!

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
