  1. Go to Settings > PBX > Call Control > Outbound Routes, click Add.

    Outbound Route Step 1
  2. Configure the outbound route.

    The system compares the number with the pattern that you have defined in your route 1. If 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.
    Adjust the outbound route sequence by clicking these buttons:


    Outbound Route Step 2

    Name: give a name for the outbound route.
    Dial Patterns: set the dial patterns. As the settings below, to make calls via the easybell SIP trunk, you need precede the number to be dialed with the prefix 8.
       Dial Pattern: 8.
       Strip: 1
    Member Trunks: select the easybell SIP trunk.
    Member Extensions: select the extensions that are allowed to make calls through the
    outbound route.
  3. Click Save and Apply Changes. Now you can make outbound calls through the easybell SIP trunk. As the dial patterns configured above, you need dial digit 8 before the destination number.
    For example, to call the number 4901234567, you need dial 84901234567 on your phone.
