Call Forwarding Telephony
N
Note: When call forwarding to the Comfort Pro A IAB voicebox programme, the “Via”
call number is evaluated in order to determine the owner of a voicebox. The last call
forwarding user is used no matter what the user group setting. When call forwarding
using the secretarial function of the voicebox programme, the call number of the
voicebox owner is also shown as the “Via” call number.
Loop Detection
Loops can generally occur during a call forwarding chain, e. g. when the call forwarding destination refers
back to the call forwarding source. This is why a forwarded call has a call forwarding history. When the next
call forwarding destination is already included in the call forwarding history, a loop is detected and any further
call forwarding is prevented. If no parallel call signalling takes place, e. g. by the Indicate call forwarding
after time parallel setting in the user group, the call is cleared when there is a loop.
Loop Detection
A loop is also detected during call diversion. When you wish to divert an incoming call to a destination call
number which is already part of the call forwarding chain, the display shows
NEG.
and call signalling is
continued.
N
Note: The call forwarding history cannot be transmitted via Q.SIG connections. Chain
detection is also deactivated when forwarding via the voice portal programme
