Practical guide

Use external forwarding only with a checked second leg

Last materially reviewed 2026-09-28

Quick answerForwarding creates another route with its own availability, charges and failure conditions.
What to know

Distinguish forwarding from porting

Forwarding redirects a call while the original service remains part of the journey. Porting changes the provider that serves the number. A forwarding arrangement may help a transition, but it does not establish that a number has moved or that the old account can be closed.

What to know

Confirm the destination and failure branch

Ask what happens if the external destination is busy, unreachable or answered by its own voicemail. Check timeout behaviour and the caller identity presented on the second leg. Do not assume the receiving mobile or another provider will behave like an internal user.

What to know

Check cost and responsibility

Confirm whether the forwarded leg is included in the plan or separately charged. Agree who owns the destination and who may change it. Keep private numbers in controlled configuration, not in public worksheets or a shared illustrative diagram.

What to know

A fictional temporary route

An office uses an authorised covering number while preparing a new system. It checks both answer and no-answer behaviour and keeps the current service active. Once the intended transfer is accepted, the team removes the temporary route only after checking the final path.

What to know

Check the second destination as well as the first

Draw the forwarding destination's own answer and no-answer behaviour. A call may leave the original platform correctly yet enter another queue, personal voicemail or a route back to the starting number. Check for that loop before relying on the arrangement. Ask the provider which charges and caller-identification behaviour apply to the proposed route rather than assuming it behaves like an internal extension. Confirm that the destination owner has agreed to receive these business calls and knows when the temporary cover ends. Keep actual numbers private and document who may change them. Acceptance should describe the useful final destination, not just a log entry saying the call was forwarded. If that destination cannot provide the intended service, reconsider the fallback.
