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.
