Path: Telephony -> Outbound Control -> Dial Permissions
A dial permission consists of outbound dial permissions (dial rules) and internal dial permissions. Each extension number had been assigned with a dial permission. Dial rules are created for dial outbound phone calls, internal dial permissions are used for controlling extension number from using local phone system features.

You may create several different dial permissions. By assigning the extension numbers with different dial permissions you may limit the extension users to dial certain outbound phone calls and use certain local phone system features.
Click on button to create a new dial permission or you may use the default dial permission.
- In the Dial Rules section by moving the dial rules from the Available Rules field to the Selected Rules field to enable the dial rules in this dial permission. In the above given example, 2 dial rules had been enabled. The “Dial-FXO” rule is used to make phone calls through CO lines (land lines). The “dial-sip-trunk” rule is used to make phone call through the SIP trunk. So if you assign this dial permission to the extension users, they will be able to make outbound phone call both through CO lines and the SIP trunk.
- In the Internal Permissions section by switching the internal call features on/off to enable/disable the call features.
- Extension: Allow/Disallow dialing other extension numbers.
- Paging & Intercom: Allow/Disallow dialing paging & intercom group numbers.
- Conference: Allow/Disallow using conference feature.
