Configure Signaling
To configure signaling
1 Go to Admin > Local Cluster > Signaling Settings.
2 To make the system accessible via H.323 calls:
a Select Enable H.323 signaling.
b Leave the default port numbers (1720 for H.225, 1719 for RAS) unless
you have a good reason for changing them.
c Select H.323 multicast to support gatekeeper discovery messages
from endpoints.
3 To make the system accessible via SIP calls:
a Select Enable SIP signaling.
b If the system’s security settings permit unencrypted SIP connections,
optionally select TCP or UDP/TCP from the list.
You must have the Administrator role to change security settings. See
“Security Settings” on page 46.
c Leave the default port numbers (5060 for TCP/UDP, 5061 for TLS)
unless you have a good reason for changing them.
4 To enable the system’s XMPP server:
a Select Enable XMPP signaling.
b If the system’s security settings permit unencrypted XMPP
connections, turn on Unencrypted XMPP port.
You must have the Administrator role to change security settings. See
“Security Settings” on page 46.
c Leave the default port numbers (5222 for unencrypted XMPP, 5223 for
TLS) unless you have a good reason for changing them.
5 Click Update.
A dialog box informs you that the configuration has been updated.
Note
The system only answers UDP calls if that transport is enabled. But for
communications back to the endpoint, it uses the transport protocol that the
endpoint requested (provided that the transport is enabled, and for TCP, that
unencrypted connections are permitted).
For more information about this and other aspects of SIP, see RFC 3261.
