To allow users to place an ISDN-to-IP call through a gateway:
1. If you want to allow users to place ISDN-to-IP calls through a gateway
when dialing manually:
a. Make sure Call Quality is enabled on the Home Screen Settings
screen. This setting displays the Call Type selection on the Place a Call
screen.
b. On the Network Dialing screen, select IP Gateway next to ISDN in the
Dialing Order.
With this configuration, users can enter the gateway address in the dialing
field, along with an extension in extension field, and select IP H323 in the
call type list.
2. If you want to allow users to place ISDN-to-IP calls through a gateway
when calling from the directory, do one of the following:
— On the Network Dialing screen, set Preferred Dialing Method to
Auto and select IP Gateway next to ISDN under Dialing Order. With
this configuration, calls placed from the directory will be placed
through a gateway first if a gateway address is present in the ISDN
number field and an extension is present in the Extension field.
— On the Network Dialing screen, set Preferred Dialing Method to
Manual. With this configuration, users can select IP Gateway from
the list of call types that appears when placing a call from the
directory.
