SIP Protocol Features
This chapter defines how to configure the SIP-specific feature to properly use the SIP signalling programs and
information defined in Mediatrix’ SIP stack.
User Agents
A user agent is a logical entity that can act as both client and server for the duration of a dialog. Each line (also
known as endpoint) of the Mediatrix 1204 is a user agent.
You can set information for each user agent such as its telephone number and friendly name. This information
is used to dynamically create the
To
,
From
and
Contact
headers used in the request the user agent sends.
These headers make up the caller ID information that is displayed on telephones/faxes equipped with a proper
LCD display. See
“Caller ID Information” on page 149
for more details.
Most of the variables related to the user agents are located in tables. You can display and define the
information for all lines. You can also use these tables to create/edit five user names and passwords per line.
This means that:
Rows 1-5 of the table are reserved for line 1.
Rows 6-10 of the table are reserved for line 2.
etc.
If you want to enter a user name for the second line, you must do so in the sixth row of the table. If you want
to enter a user name for the third line, you must do so in the eleventh row of the table, and so on.
Before changing a parameter value, build its corresponding table with your MIB browser’s table functionality.
Depending on the MIB browser you are using, the tables may not appear the same way.
You can also set these parameters via the web interface, as described in
.

To set basic user agent information:
1.
In the
sipMIB
, set the user agent port number in the
sipPort
variable.
The default value is 0. If
sipPort
is set to 0, the default SIP port is used.
2.
In the
sipUAIfTable
group, set a main user name in the
sipUAMainUsername
variable.
The main user name uniquely identifies this endpoint in the domain, such as a telephone number.
It is used to create the
Contact
and
From
headers. The
From
header carries the permanent location
(IP address, home domain) where the endpoint is located. The
Contact
header carries the current
location (IP address) where the endpoint can be reached. Contact headers are used in two ways:
•
First, contacts are registered to the registrar. This enables callers to be redirected to
the endpoint’s current location.
•
Second, a contact header is sent along with any request the user agent sends (e.g.,
INVITE), and is used by the target user agent as a return address for later requests to
this endpoint.
3.
Set a display name in the
sipUADisplayName
variable.
This is a friendly name for the user agent. It contains a descriptive version of the URI and is intended
to be displayed to a user interface.
4.
Restart the Mediatrix 1204 so that the changes may take effect.
