Call Forwarding Unconditional is used immediately, i.e.without a delay, for all incoming calls.

You can activate Call Forwarding Unconditional:

Calls are forwarded to your standard Voicemail or to the given number, depending on your configuration.

You can also change Immediate Call Redirection from another telephone line (see This is how you change the settings for Forwarding Unconditional per Remote Inquiry).

If Call Forwarding Unconditional is not activated, you can also delay the forwarding of calls (see also chapter Call Forwarding No Reply) or, if you are already telephoning, you can forward calls individually (see also chapter Call Forwarding Busy).
