Unanswered Question
Dec 1st, 2008

Hi Guys,

My Customer have the following configuration/topology: It have 02 CallManger version 3.1.3, a one work Publisher and another Subscriber. It configured each callmanager to work with dhcp server. It is occuring the following problem: The Publisher the range is up mask and Subscriber the range is up the same mask. When Publisher stayed down the IP Phones pass to register in Subscriber, but, when subscriber stayed down the IP Phones not change to Publisher. The problem can be a any configuration is Cisco CallManager or not?

Thank You,


I have this problem too.

Does the device pool referenced by the phone include a CM group that lists both CallManager servers?

Is CCM service running on the Pub?
