1.30.4.3 Call Forwarding (CF)—by QSIG
Description
The PBX forwards the call to a destination extension in another PBX in QSIG network. The destination can
be set on your own PBX on an extension basis as the forward destination of trunk calls (→ 1.3.1.2 Call
Forwarding (FWD)).
If the same trunk group is used for the incoming call and the forwarded call, the following situation will be
possible.
Conditions
• This feature complies with European Telecommunication Standard (ETS) specification ETS 300 257,
Diversion supplementary services.
• This feature can be enabled or disabled on each ISDN (QSIG) port of the PBX.
[Example]
Extension 1000 of PBX-1 dials extension
number "2000", and the call is sent to
extension "2000" of PBX-2 through QSIG
network.
The call is forwarded to the forward
destination of trunk calls of extension
2000, which is extension "1001" of PBX-
1.
The call between PBX-1 and PBX-2 is
released, and the call is connected
directly to the forward destination of
extension 2000.
