How to configure manual call forwarding for intercom calls?

Set up manual forwarding to redirect unanswered calls from a virtual number to other numbers, including mobile phones via SIP trunks.

1. Go to Telephony settings → Forward rules and click the ➕ icon in the lower-left corner.

2. Enter a name for the rule.

3. Under Forward settings, define when the forwarding should trigger — immediately or after a delay.

4. Select one of the call forwarding modes:
    • Immediately — calls will be forwarded to the first call queue without delay;
    • If no answer within X seconds, busy or error, then forward to — calls will be forwarded to the next queue only if the previous one fails, is busy, or not answered within the defined time.

Open

5. Click ➕ Add call queue, then click the ➕ icon inside the queue → select Virtual number or Phone number.

6. If entering a mobile number:
    • enter it in international format (e.g. +447975777666);
    • click ✓ to confirm;

7. Add multiple queues or delays if needed.

8. Click 💾 Save in the bottom-left corner.

If you want to configure call forwarding directly for a specific virtual number, you can set it up individually without creating a global rule.

Go to Telephony settings → Virtual numbers, then click the ✏️ next to the number you want to edit. In the Forward settings section, select Manual settings. This lets you define call queues and conditions right inside the number, using the same options as in a global rule.
