Hi,

I would like to find out if it is possible to modify the firmware to support 3rd party call manager if I have a valid contract.

Rath,

None of the information in that thread is applicable anymore. There is a specific set of instructions and requirements to go from Enterprise to 3PCC and viceversa which is something that you can do now.

At the time of that thread, the only possible migration path could have been from 3PCC to enterprise, the other path didn't exist at the time.
