One task and project complete. PSTN call outbound rule

I have a PSTN number 2261234. I want to setup outbound rules so that only desired person could call outbound. And any one could call my internal VoIP phones.

I also want to install Digium 4 Port Analog Card in Asterisk NOW 10.0.

Please Help!

If using Asterisk Now it use FreePBX for basic system administration, so I suggest you contact the FreePBX forum, related to the card installation make sure dahdi driver is installed and loaded correctly and you use the GUI to configure the card at least on currents versions of FreePBX
