ISDN BRI ETSI Call Forwarding Unconditional
The ISDN BRI ETSI Call Forwarding Unconditional (CFU) supplementary service allows an
incoming call to an ISDN BRI terminal to be forwarded to a predetermined destination, within
or outside the system. The call is forwarded whether the user is busy or idle.
An ISDN BRI user can assign the same address or a different address for voice or data calls
being forwarded. Calls can also be forwarded to an ISDN BRI terminal or a non-ISDN BRI
terminal. When the CFU feature is activated, outgoing calls can still be made from the ISDN
BRI terminal.
The ETSI supplementary service provides Call Forwarding capabilities to all users on the
access (that is, all the DNs defined under a Digital Subscriber Loop (DSL), or an individual
user (that is, a DN).
Perform an ISDN BRI ETSI Call Forwarding Unconditional test
The following test is for forwarding a voice call from an ISDN BRI M5317 set.
1. Set up ISDN BRI ETSI Call Forwarding Unconditional in Overlay 27 (refer to the
"Configuring ISDN BRI features" chapter in Avaya ISDN Basic Rate Interface
Feature Fundamentals (NN43001-580).
a. Select the ETSI protocol for the DSL.
b. Configure the call type (enter voice call type) and Call Forward (enter
voice call forward).
2. On the ISDN BRI terminal, configure ISDN BRI ETSI Call Forward Unconditional.
3. Configure two DN appearances on the ISDN BRI terminal (use the first DN to
forward a call, and the second DN to place a call to test the call forward). On some
ISDN BRI terminals, the second DN appearance allows the user to initiate the
second call.
4. Activate ISDN BRI ETSI Call Forwarding Unconditional on the ISDN BRI terminal,
for the first DN:
a. Press the Forward key.
b. Dial the number where calls are to be forwarded.
c. Press the Forward key.
Note:
Call Forward Reminder Tone should be provided to the ISDN BRI terminal.
