Add Guest Prefix Dialog Box

The Add Guest Prefix dialog box appears when you click the Add button next to the Unauthorized prefixes list in the SIP Settings section of the Signaling Settings page. It lets you add a prefix to the list of prefixes used for “unauthorized” or “guest” calls.

The following table describes the fields in the Add Guest Prefix dialog box.

Table 4-8	Add Guest Prefix dialog box
Field		Description
Prefix		The prefix number for this entry.
		This is the number that an SBC is configured to add to
		the Request-URI of the first INVITE message for
		untrusted calls to the DMA system.
Strip prefix		Check this box to have the system immediately strip this
		prefix from the INVITE message.
Authentication		Select one of the following:
		• None — The system doesn’t issue authentication
		challenges or check authentication credentials for
		calls with this prefix.
		• Authenticate — The system issues authentication
		challenges and checks authentication credentials
		for calls with this prefix.
		The settings on the Device Authentication page
		(see “Device Authentication” on page 264)
		determine the realm used for authentication and
		whether the Call Server responds to
		unauthenticated requests with 401 (Unauthorized)
		or 407 (Proxy Authentication Required).
		• Block — The system blocks calls with this prefix.
