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: ISDN Gateway vs. H.323<->SIP Gateway

This feature is not related to the Polycom RealPresence 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 133).

The following table describes the fields in the dialog box.

Column	Description
Name	A display name for this service.
Description	Brief description of the service.
Enabled	Clearing this check box lets you turn off the service without deleting it.
Simplified ISDN dialing prefix	The dial string prefix(es) assigned to this service.
	Enter a single prefix (44), a range of prefixes (44-47), multiple prefixes
	separated by commas (44,46), or a combination (41, 44-47, 49).
	If your dial plan uses the Dial services by prefix dial rule (in the default dial
	plan) to route calls to services, all dial strings beginning with an assigned
	prefix are forwarded to this service for resolution.
Use all ISDN gateways	Indicates whether this service applies to all available gateways or only those
	selected below.
Available ISDN gateways	Lists the ISDN gateways that have at least one session profile specifying an
	H.320 or PSTN protocol. See Edit MCU Dialog Box on page 133.
Selected ISDN gateways	Lists the selected ISDN gateways. The arrow buttons move gateways from
	one list to the other.
