4. Define whether or not to override the default proxy home domain used by entering a domain in the
SIP Domain field.
This value replaces the home domain proxy host as defined in the Proxy Host field. It is used by the
address of record in the To and From headers.
5. If the SIP server configuration source is Static :
• enter the SIP registrar server static IP address or domain name in the Registrar Host
field.
• enter the SIP registrar server static IP port number in the Registrar Port field.
• enter the SIP Proxy server static IP address or domain name in the Proxy Host field.
• enter the SIP Proxy server static IP port number in the Proxy Port field.
• enter the SIP outbound proxy server static IP address or domain name in the Outbound
Proxy Host field.
Setting the address to 0.0.0.0 disables the outbound proxy.
• enter the SIP outbound proxy server static IP port number in the Outbound Proxy Port
field.
• enter the SIP Presence Compositor server static IP address or domain name in the
Presence Compositor Host field.
• enter the SIP Presence Compositor server static IP port number in the Presence
Compositor Port field.
6. Specify whether a line should remain enabled or not when not registered in the Unregistered Port
Behavior field.
This is useful if you want your users to be able to make calls even if the line is not registered with
the SIP server. The following values are available:
7. Click Submit if you do not need to set other parameters.
The current SIP server information is displayed in the SIP Info section.
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 4104 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.
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.
Table 43: Unregistered Line Behaviour
Value Description
disable port When the line is not registered, it is disabled. The user cannot make or
receive calls. Picking up the handset yields a fast busy tone, and incoming
INVITEs receive a “403 Forbidden” response.
enable port When the line is not registered, it is still enabled. The user can receive and
initiate outgoing calls. Note that because the line is not registered to a
registrar, its public address is not available to the outside world; the line will
most likely be unreachable except through direct IP calling.
