[cisco-voip] SIP trunk - how to make it redundant - CM6 to OCS 2007

[Brian Van Benschoten]

I'm setting up a SIP trunk between CM6.01a and our OCS 2007 environment.

My question is how do you configure redundancy in this setup.

I have a publisher and subscriber in my cluster, but the OCS side wants
to build a SIP trunk to a SINGLE ip address.

If I build the SIP trunk between the CM subscriber and the OCS box and
the subscriber goes down, is my SIP trunk gone ?

My publisher would still be up, the SIP trunk would register with the
publisher but now the IP address of its endpoint would be the publisher
and OCS most likely wouldn't like that.

 

I think this issue exists with any type of SIP trunk on call manger.  To
CUPS or a 3rd pary PBX too.

 

Any ideas how to work thru this?
