We have a CCM server cluster working with two CCM servers, one as the publisher and the other as the subscriber. We have 7940G, 7960G and 7912 and 7911 models of IP phones working.
Recently we have updated the firmware of 7940/7960 ip phones to 8.0.7, and then on if the primary CCM goes down these 7940/7960 ip phones do not get registered with the secondary CCM. However all the other ip phone models are working fine (they get registered to the secondary CCM incase of primary fails). We are using DHCP to assign IP addresses to the ip phones and the tftp option on the DHCP server is fine (its configured with both the CCM's ip addresses).
Can someone give your inputs to solve this issue pls...
