External Call Forwarding
Description
External Call Forwarding (ECF) allows an incoming Trunk to be re-directed to another location through
the use of another Trunk. When a Trunk senses incoming ringing, it answers the call and accesses
another Trunk. It then chooses a pre-programmed system speed dial number, dials the call and connects
the two Trunks together.
Conditions
Externally Forwarded calls are subject to a call duration limit of 6 minutes. This limit may be extended by
dialing any numeric DTMF digit when the expiration tone is heard (approximately 10 seconds before
disconnect). This will extend the allowed duration by an additional 6 minutes.
A CO line must be available in order for an external call forward to occur.
The digit [*] can be dialed to immediately disconnect the call.
Programming
If a Voice Service Unit is present in the system, you may choose to program a message that will be
played while a call is being externally forwarded. This informs the outside caller that the call is being re-
routed. If the message is desired, Mode 14 must have one channel programmed as a call forwarding
message. For more information on this, see Voice Service Unit, page 184 of this document.
Mode 35-[TK]-03, External Call Forward Destination. In order for External Call Forwarding to operate, a
speed dial number must be selected for ECF to utilize in the process of forwarding. Valid settings for this
option are listed below:
