Gurus,
I have a call manger running 8.6 and have to change the subnet mask to allow for an expanded scope. Will this cause a problem with the ITL the way changing the IP address will? I don't want to blow up all the phones if I can avoid it.
Thanks!!
Are you changing the IP address of the phones
Or the IP of CUCM?
