Hi Antonis,

What you want is to implement COR Lists on CME in order to restrict internal calls between the specified extensions and allow all other extensions make calls through the PSTN/SIP.

Cor Lists are a bit of a challenge until you understand how they work. You can read up on them here:
www.cisco.com/c/en/us/support/docs/voice...configuring-cor.html

We are also planning to cover COR Lists in the near future on Firewall.cx.

Here is a template I use to help me speed up the rollout of COR Lists on new installations. You must read the above link first in order to understand their logic and the below configuration will make more sence to you.

Good Luck!
