Will changing the subnet mask cause problems?


Customer wants to change the subnet mask on the network that houses the UCM and phones. Any potential problems foreseen?


If you change everything accordingly, I don’t see any problems.


Depends which way the subnet mask is eg if it is a and you want to have two networks reachable and go to / and etc … then that wont be a problem.

If it is a different scenario to that then you will have to edit all network interfaces to suit.
