2. B channel

The call forwarding is performed by the PBX during a call. It is possible
for all exchange line types but requires a free voice channel and the number
of the caller cannot be displayed unless CLIP no scrrening is used which is
not supported by many providers.
For call forwarding via the PBX, use any available call channel
Requirements:
• Enabled call forwarding method 2. B channel

When an external phone number is forwarded, the call can be
forwarded via a call channel on any of the other ports.

A call can only be redirected via a call channel on the same port. The
probability that the call cannot be forwarded because the channels are busy
is therefore higher.
Renouveler le transfert d'appel en cas de redémarrage du système

When rebooting the PBX, the saved data of the call forwarding is
renewed.
Important: In Switzerland, the configuration of a call forwarding is
chargeable. To avoid costs, the check box must be disabled.
