Add Simplified ISDN Gateway Dialing Prefix Dialog Box

The Add Simplified ISDN Gateway Dialing Prefix dialog box lets you create a new prefix-driven simplified ISDN gateway dialing service for using external ISDN gateways.

Note

This feature is not related to the Polycom DMA system’s built-in H.323<->SIP gateway. Simplified ISDN gateway dialing is for routing calls to H.320 or PSTN protocol gateways.

This feature isn’t supported for calls from SIP endpoints, but SIP endpoints can make ISDN gateway calls by directly calling an MCU/gateway using its direct dial-in prefix (see “Edit MCU Dialog Box” on page 142).

The following table describes the fields in the dialog box.
