How to Divert Calls on BT Business Landlines
Managing your business calls effectively often means diverting your landline to a mobile or to a missed-call text-back service when you are busy. This guide covers the essential star codes and methods for BT Business users.
1. Immediate Diversion (All Calls)
This setting redirects every incoming call to your chosen number immediately, without your desk phone ringing at all.

To cancel: Press # 21 #

2. Divert on No Reply
This allows your desk phone to ring first. If you don't answer within a certain time (usually 15-20 seconds), the call is diverted.

3. Divert when Busy
Redirects calls only when you are already on another call.

The smarter place to divert to
Diverting your BT line to a mobile just means you still have to answer it. Divert it to your Call2SMS number instead and the calls you can’t take get handled for you:

- A quick, friendly conversation captures their name and what they need.
- The lead lands on your phone — ready to call back and win the job.
