SIP Server
Realm Name A realm is a set of usernames and passwords used by SIP client devices
to authenticate with a SIP server. The X6004 supports a single realm.
When SIP clients register with the X6004, they must provide the name
of the realm they belong to as well as the username and password.
Type the realm name which the extensions that register with the X6004
must provide for authentication.
Port Enter the X6004’s listening port number or keep the default value. This
is the port number your SIP clients need to use to register with the
X6004.
You can also enter up to two different alternate ports.
