Add Guest Port Dialog Box
The Add Guest Port dialog box appears when you click the Add button next to the Unauthorized ports
list in the SIP Settings section of the Signaling Settings page. It lets you add a port to the list of ports used
for “unauthorized” or “guest” calls.
The following table describes the fields in the Add Guest Port dialog box.
Require certificate
validation for TLS
Check the box to enable mutual TLS (mTLS), requiring each caller to present
a valid certificate.
Unauthorized ports Lists the ports used by your SBC(s) for untrusted calls, showing the transport
type for each and, for TLS, whether a certificate is required. The
Authentication column indicates whether calls to that port are passed without
challenge, challenged for authentication credentials, or blocked.
Click Add to add a port to the list (see Add Guest Port Dialog Box on
page 76). Click Edit to edit the selected entry (see Edit Guest Port Dialog Box
on page 77) or Delete to delete it.
Unauthorized prefixes Lists the prefixes used by your SBC(s) for untrusted calls. The Strip Prefix
column indicates whether the RealPresence DMA system should immediately
strip the prefix. The Authentication column indicates whether calls to that
port are passed without challenge, challenged for authentication credentials,
or blocked.
Click Add to add a prefix to the list (see Add Guest Prefix Dialog Box on
page 78). Click Edit to edit the selected entry (see Edit Guest Prefix Dialog
Box on page 79) or Delete to delete it.
