In our network , there are two call manager groups ( GP1, Gp2)
There are two device pools ( DP1, DP2)
For GP1 group , active call manager is 172.16.9.1 standby 172.16.9.2 ( all ip phones belongs to DP1 device pool connected to this group)
For GP2 group , active call manager is 172.16.9.2 standby 172.16.9.1 - (all ip phones belongs to DP2 device pool connected to this group)
For all ip phones in both device pools , tftp server configured manually as 172.16.9.1 ( publisher)
I am not able to reset/change setting of phones belongs to DP1
When I changed device pool of IP phone to DP2 ( means active call manager is the subscriber ), the phone get reset first by power reset & then I am able to configure settings.
If i changed it back to DP1 pool, once the configuration loaded into the phone as usual, again i am not able to reset /change settings by call manager..
Can anyone give me some idea of what's gone wrong here !
