Start by identifying whether the number is a mobile line, a fixed business line or part of a telephone system. Use the guidance for that service; the same setup method should not be assumed to apply to all three.

## Official starting points

Türk Telekom publishes a [mobile call-forwarding service page](https://bireysel.turktelekom.com.tr/dijital-servisler/arama-servisleri/cagri-yonlendirme) with setup methods and service terms. For a fixed business line, use its [business telephone service guidance](https://kurumsal.turktelekom.com.tr/is-telefonu/servisler/kullanim-kolayliklari).

Confirm current eligibility, charges and the method for your line with Türk Telekom. These references explain carrier services; they are not confirmation that a particular Golub Voice destination has been tested with your plan.

## Prepare the setup

1. Identify the line owner and the exact line being changed.
2. Get the intended destination from your Golub Voice setup.
3. Decide which condition should forward: all calls, no answer, busy or unreachable, where available.
4. Review the corresponding official instructions and the current forwarding or voicemail settings.
5. Keep the restoration method before applying a change.

Do not reuse codes or sample numbers from an unrelated line type. Follow the carrier’s current guidance for the number format and activation method.

## What to check afterwards

Plan to verify the chosen condition, the expected agent greeting and the fallback when the destination cannot answer. If the line is managed by a business telephone system, check whether an administrator must also adjust that system’s route.

If a setting is rejected, retain the non-sensitive error message and ask Türk Telekom to confirm whether the line and destination are eligible.
