The dial plan applies for callback calls. Go to Wallboard > Queue management > Settings > Dial plan > Configure > Update:
For example: if you want to call SG numbers without dialing 65, please configure a dial plan as below:
- If number starts with: 3,6,8,9
- and has a length of: 8
- Remove number of leading digits: 0
- then prepend prefix: 65
