	Field	Description
	Dialing method	The ISDN inward dialing method for the site:
		• DID (Direct Inward Dial). Select this option if your
		ISDN gateway is provisioned with a range of phone
		numbers from the ISDN service provider, and each
		of these numbers will be assigned to an endpoint as
		an alias.
		• Gateway Extension Dialing. Select this option if
		your ISDN gateway’s ISDN connection is
		provisioned with a single gateway phone number
		from the ISDN service provider, and endpoints will
		be assigned an extension (E.164 alias) that’s
		internal to the company and doesn’t correspond to
		any number that can be dialed on the PSTN.
		Endpoints can be dialed from the PSTN by dialing
		the ISDN gateway phone number, followed by a
		delimiter (usually a #) and the extension number.
		The gateway receives the full number from the
		PSTN and dials only the extension number on the
		IP network.

		rules, is usually accurate for placing outbound calls.

		through the site’s PBX when dialing out.

		of the call’s destination.
	Area code	The city or area code for the site’s location. Leading
		zeroes are optional. For example, the city code for Paris
		is 01, but you can enter either 01 or 1 in this field.

		area code of the gateway site with the area code of the
		call’s destination.
