Configure the Outbound Route with FreePhone Trunk

To make outbound calls via the newly created SIP trunk, you need to configure an outbound route for the trunk.
1. Create an Outbound Route
Go to Settings > PBX > Call Control > Outbound Routes, click Add.

2. Configure the Outbound Route
The system compares the number with the pattern that you have defined in your route 1. If it matches, it will initiate the call using the selected trunks. If it does not, it will compare the number with the pattern you have defined in route 2 and so on. The outbound route which is in a higher position will be matched firstly.
You can adjust the outbound route sequence by clicking these buttons

  • Route Name: give this outbound route a name to help you identify it.
  • Dial Patterns: set the dial patterns. As the settings below, to make calls via the SIP trunk, you need to precede the number to be dialed with the prefix 8.
  • Dial Pattern: 8.
  • Strip: 1
  • Member Extensions: select the extensions that are allowed to make calls through the outbound route.
  • Member Trunks: select the FreePhone trunk.

3. Click Save and Apply
Now you can make outbound calls through the FreePhone trunk. As the dial patterns configured above, you need to dial “8” before the destination number.
For example, to call the number “4801234567”, you need to dial “84801234567” on your phone.

Configure the Inbound Route with FreePhone Trunk

To specify how calls from the FreePhone trunk should be routed, you need to configure an inbound route for the SIP trunk.

When you call in the SIP trunk, the call will be routed to the destination configured on the inbound route.
