Phone Calls Restriction
You may restrict the direction of calls for the entire company, for specific departments or employees for security reasons.
For example, in the accounts department, you may limit all calls except for internal ones. The manager for international sales makes calls to America, whereas ordinary managers will be able to call only within Russia.
The functional limits calls from SIP phones and softphone only. It does not limit calls from mobile phones.
Note! In the PBX, all outgoing calls to ANY city and mobile numbers are carried out with a city code.
