To configure signaling
1Go to Admin > Local Cluster > Signaling Settings.
2To make the system accessible via H.323 calls:
aSelect Enable H.323 signaling.
bLeave the default port numbers (1720 for H.225, 1719 for RAS) unless
you have a good reason for changing them.
cSelect H.323 multicast to support gatekeeper discovery messages
from endpoints.
3To make the system accessible via SIP calls:
aSelect Enable SIP signaling.
bIf 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.
cLeave the default port numbers (5060 for TCP/UDP, 5061 for TLS)
unless you have a good reason for changing them.
4To enable the system’s XMPP server:
aSelect Enable XMPP signaling.
bIf 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.
cLeave the default port numbers (5222 for unencrypted XMPP, 5223 for
TLS) unless you have a good reason for changing them.
5Click 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.
