Call Forwarding: A Complete Guide
Call Forwarding: A Complete Guide
This guide covers everything you need to know about call forwarding for UK mobile users and businesses.
How Call Forwarding Works
Call forwarding (also called call diverting) redirects incoming calls from your mobile to another number — a landline, another mobile, or a VoIP system. This ensures you never miss important calls, even when you are away from your phone.
Types of Call Forwarding
- Unconditional (all calls) — every call is forwarded immediately, your phone does not ring.
- When busy — calls forward only when you are already on another call.
- When unanswered — calls forward after a set number of rings.
- When unreachable — calls forward when your phone is off or out of signal.
Call Forwarding Codes
| Action | Code |
|---|---|
| Forward all calls | **21*[number]# |
| Forward when busy | **67*[number]# |
| Forward when unanswered | **61*[number]# |
| Forward when unreachable | **62*[number]# |
| Cancel all forwards | ##002# |
Business Call Forwarding
For businesses, call forwarding is essential for ensuring customer calls are always answered. A hosted VoIP system offers much more sophisticated routing — time-based rules, ring groups, hunt groups and auto attendant — without the limitations of basic mobile call divert.
