Call forwarding

Forward calls from your business mobile

Open the dialler, type **21* then the destination number in full international format, then #, and press call: every incoming call now goes to that number.

The busy, no answer and unreachable versions use the same pattern with different digits. All four are below.

The codes

Four types, and what to dial for each

Replace number with the destination in full international format: +447700900123, not 07700 900123. Tap a code to copy it.

Every callDiverted before the phone rings. For a day away from the desk.
When you are busyOnly when you are already on another call.
When you do not answerAfter the handset has rung out. Sends it to a colleague or reception.
When you are unreachablePhone off, in flight mode or out of coverage.

Dial and press call; the network confirms on screen. The three conditional types can run together, each to a different number. Forwarding every call overrides all of them.

Questions

What it costs, and how to undo it

Does call forwarding cost anything extra?

Turning call forwarding on is free. The forwarded leg of the call is not: when a call is diverted, you pay for the call from your line to the destination number at your standard tariff rate. Forwarding to a UK mobile is charged at UK rates, and forwarding to a number abroad is charged at the international rate for that country.

Can I forward calls to an international number?

Yes. Enter the destination in full international format, starting with the country code, such as +971 for the United Arab Emirates or +1 for the United States. International call rates apply to every forwarded call.

Can I use more than one forwarding type at the same time?

Yes. The three conditional types can run together and can each point at a different number, so a call can go to a colleague when you are busy and to reception when you do not answer. Unconditional forwarding overrides all of them, because it diverts the call before the phone rings.

Rates for forwarding abroad are on the business international rates page. On a Cloud PBX extension, forwarding is set in TISA Cloud PBX rather than on the handset.
