we have in our company two CME router and we make HSRP betwwen the two CME to make the redandancy and the redundancy is working fine ...
the problem is we have some of the Phones are connected through DSL ( direct connection ), sometimes we found the phone not register to the active CME and when we open the HTTP page for the phone and going to the Network configrations menu it shown that the Callmanager 1 is Standby!!!!!!!
and the phone is sending standby keepalive to the CME all the time
when we reset the phone it's working fine and after some time this problem happen again
