Figure 3-10 Voice Call Routing Default Setting
Note the phone port check marks for each telephone
number. This default configuration routes each telephone
number to a specified port.
The ISDN Call Waiting default configuration is best served by
the recommended scenario shown in Figure 3-10. By default,
ISDN Call Waiting has been enabled on Phone Port 1, for use
with your telephone, but disabled on Phone Port 2 to prevent
potential interruption of calls to your fax machine (S76=1).
One Telephone Number and Two Analog Devices.
If you have only one telephone number for your ISDN line
and two analog devices, check the Phone Port 1 and Phone
Port 2 boxes located in the Number 1 group box, as shown in
Figure 3-11. Calls to that telephone number will ring both
devices, allowing you to answer a call using either device.
