Preparing router to act as a CME:
- configure ip address on interface.
- Configure the source address, the IP address to which ip phones will register:
- specify the maximum number of phones that CME can handle. This will affect the router performance:
- configure the maximum number of ephone-dns:
Later, I will change these values because my router lacked memory resources.
To verify the aforementioned settings:
Let’s create our first ephone-dn:
At this point, my router displayed an error message indicating a lack of memory. I increased its memory size in GNS3:
After a reload, things went ok
I also reduced the max-ephone and max-dn values:
Now we can add ephone-dns without problems:
When I create a dual-line ephone-dn, two “sub-ephone-dn” are created:
To verify ephone-dns:
another way to verify it:
Notice that there are two channels for ephone-dn 2, which is a dual-line ephone-dn.
Adding a secondary line to a dual-line ephone-dn:
