Configuring Dialing Order Settings

If the call type on the home screen is set to a specific call type, the system does not attempt to place the call using a different call type, even if other types are listed in the Dialing Order.

You can configure the VSX system so that users can choose to place IP-to-ISDN or ISDN-to-IP calls through a gateway.

To allow users to place an IP-to-ISDN call through a gateway:

1.Make sure the system is registered with a gatekeeper.

2.Go to System > Admin Settings > Network > Call Preference and select Enable ISDN Gateway.

3.If you want to allow users to place IP-to-ISDN 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 ISDN Gateway as the first choice under Dialing Order. With this configuration, calls placed from the directory will be placed through a gateway first if an ISDN number exists.

—On the Network Dialing screen, set Preferred Dialing Method to Manual. With this configuration, users can select ISDN Gateway from the list of call types that appears when placing a call from the directory.
