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.
Require certificate validation for
TLS
For TLS transport, check this box to enable mutual TLS (mTLS), requiring
callers to present a valid certificate.
Note: If Skip certificate validation for encrypted signaling is turned off on
the Security Settings page, then Require certificate validation for TLS is
turned on for both authorized and unauthorized ports, and it can’t be turned
off. See Security Settings on page 50.
Authentication Select one of the following:
•None — The system doesn’t issue authentication challenges or check
authentication credentials for calls to this port.
• Authenticate — The system issues authentication challenges and checks
authentication credentials for calls to this port.
The settings on the Device Authentication page (see Device
Authentication on page 261) 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 to this port.
Field Description
