Hello,
First of all, I apologize if I have opened the subject in the wrong place.
There are two different telephone switchboards in the institution I work for and they are not Cisco. I made the DHCP configuration via Cisco router and made the following configuration for the first switchboard on DHCP:
option 150 ip 192.168.1.11
My phones are also registered on the second switchboard, but when the communication between the router and the first switchboard goes down, it strains the first switchboard due to the command above. At this stage, I want the command to be changed as follows:
option 150 ip 192.168.2.21
It is not necessary to change, it is enough for my phones to register to the second switchboard. How can I provide this on the router? I looked in many places but I could not find anything like this.
Thanks.
