SRST Question

Hi

If you have a router that supports 100 ip phones in SRST mode but have 120 phones, is there a way of deciding which phones will not register?

regards

Re: SRST Question

Create two device pools on CCM/CUCM and assign one of the device pools with the appropriate SRST reference and leave the other one set to default. From there you are able to create your Cor list's as needed on your SRST device and know that the appropriate devices are able to register.

You can use max-phones

or ACLs to restrict specific IP/subnets or not add the SRST reference for the Phones u dont want to register in SRST mode
