Signaling Settings Local Cluster Configuration
Polycom, Inc. 69
H.323 multicast Enables the system to support gatekeeper discovery
(GRQ messages from endpoints) as described in the
H.323 and H.225.0 specifications.
SIP Settings
Enable SIP signaling Enables the system to receive Session Initiation
Protocol (SIP) calls.
Caution: Disabling SIP terminates any existing SIP
calls. When you click Update, the system prompts you
to confirm.
Unencrypted SIP port If Security Settings settings permit unencrypted SIP
connections, you can select either TCP or UDP/TCP
from the list.
We recommend using the default port number (5060),
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 (5061),
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 SIP signaling is enabled, TLS is automatically
supported. Unless unencrypted SIP connections are
specifically permitted, TLS must be used. See “Security
Settings” on page46.
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.

If Security Settings settings permit unencrypted XMPP
connections, 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.
