SIP User Agent
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.

To set user agent information:
1. In the second SIP Configuration section of the SIP page , enter a user name for each port in the User
Name column.
Figure 29: SIP – User Agent section
The 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.
2. Enter another name for each line in the Display Name column.
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.
3. Click Submit if you do not need to set other parameters.
Note:
If the port number corresponds to a domain name that is bound to a SRV record, the port must be
set to 0 for the unit to perform DNS requests of type SRV (as per RFC 3263). Otherwise, the unit will not use
DNS SRV requests, but will rather use only requests of type A because it does not need to be specified
which port to use.
