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 page77). Click Edi t to edit the selected
entry (see “Edit Guest Port Dialog Box” on page78) 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
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 79 ). Click Edit to edit the
selected entry (see “Edit Guest Prefix Dialog Box” on
page80) or Delete to delete it.
XMPP Settings
Enable XMPP signaling Enables the system to act as an Extensible Messaging
and Presence Protocol (XMPP) server for chat and
presence services.
Caution: Disabling XMPP terminates any existing
XMPP logins. When you click Update, the system
prompts you to confirm.
Unencrypted XMPP
port If security settings permit unencrypted XMPP
connections (see “Security Settings” on page 48), you
can turn it on here.
We recommend using the default port number (5222),
but you can use any value from 1024 to 65535 that’s not
already in use and is different from the TLS port.
TLS port Specifies the port number the system uses for TLS.
We recommend using the default port number (5223),
but you can use any value from 1024 to 65535 that’s not
already in use and is different from the UDP/TCP port.
If XMPP signaling is enabled, TLS is automatically
supported. Unless unencrypted XMPP connections are
specifically permitted, TLS must be used. See “Security
Settings” on page48.
