X6004 User's Guide
DESCRIPTION
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.
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.
The X6004 is a SIP registrar server. A SIP registrar server maintains a database of
SIP identity-to-IP address (or domain name) mapping. The X6004 checks your
username, password and realm when you register.
Enter the number of seconds SIP clients are registered with the X6004 before their
registration record is deleted. SIP clients should be configured to automatically try
to re-register with the X6004.
Make sure that the client SIP devices are configured to re-register at an interval
smaller than the time set in this field.
When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is
used to handle voice data transfer.
Enter the listening port number(s) for RTP traffic or keep the default values. Enter
the port number at the beginning of the range in the first field and enter the port
number at the end of the range in the second field.
Specify for how many seconds the X6004 sends a ringing tone to client devices for
incoming calls.
Select Enable to turn on support for G723.1 voice codec or select Disable to turn
off support for the G723.1 voice codec.
Note: This setting only takes effect after a system restart.
