Delay time for Call Forwarding on no reply in the PBX
This delay time for external numbers specifies the time (in seconds) after
which a call is forwarded if the called subscriber does not respond.
Note: The waiting time applies only to call forwarding that was set up
using the PBX. If the network provider has configured the call forwarding
function, the waiting time depends on their settings and cannot be
configured in the PBX.
Routing via exception numbers (VoIP + GSM)
Requirements:
• Configured exception numbers (page Routage > Routage VoIP/GSM >
Numéros de téléphone d'exception)
• Enabled call forwarding method 2. B channel

The device checks whether the destination number involved in call
forwarding for external numbers has been set up as an exception number.
If so, the call is sent along the configured path. If the destination number has
not been entered in the routing table, the call to be forwarded is sent either
via a free call channel that is assigned to the port or via any free call channel
(For call forwarding via the PBX, use any available call channel).
