Doorphone Call Forwarding to CO Line
Description
Allows the system to forward doorphone calls to ISDN lines. The extension user can change
the forwarding destination, to an extension or outside party, for each doorphone. If an outside
party is selected, calls from the doorphone are forwarded to the destination assigned in
programme "[021-022] Doorphone Call Forwarding — Day/Night." If an extension is selected,
calls from the doorphone are forwarded to the destination assigned in programme "[607-608]
Doorphone Ringing Assignment — Day/Night."
Conditions
• Class of Service programming determines the extension users who can forward the
doorphone calls to ISDN lines.
• If the transferred call is not answered within the programmed intercept time, the line will
be disconnected.
• If the doorphone button is pressed again before the call is answered, the intercept timer
starts again.
• If a call between a party at a doorphone and an outside party is established with this feature,
the duration of the call period may be restricted depending on the setting of the system
timer.
• When a doorphone call is transferred to an outside party, either the extension at Jack 1-1 or
Operator 1 can be selected for the charge account.
• If at least 1 feature has been changed from the default setting, you normally hear dial tone
2 when going off-hook. However even if you set this feature, dial tone 2 will not be heard.
• The Doorphone Call Forwarding to Outside Line button light shows the current status as
follows:
Off: This feature has not been set.
Red on: This feature has been set.
