I have a cluster of call manager 5.1.3 with 1 pub and 1 sub. My problem is that I don't get that the sip phones register in the second server when the first one goes down. I mean I have not cluster for the sip phones.
The sip phone are linksys, and in his web config I can enter only 1 proxy server (ip or name). How can I get that the cluster works for the sip phones?
