SIP Servers
The Mediatrix 1204 uses three
1
types of servers:
Proxy server
Outbound Proxy server
Presence Compositor server
This chapter describes how to configure the Mediatrix 1204 to properly use these servers.
You can also set these parameters via the web interface, as described in “SIP Servers Configuration” on
page 65 .
Proxy Server
The proxy server is an intermediary program that acts as both a server and a client for the purpose of making
requests on behalf of other clients. A proxy server primarily plays the role of routing, which means its job is to
ensure that a request is passed on to another entity that can further process the request. Proxies are also
useful for enforcing policy and for firewall traversal. A proxy interprets, and, if necessary, rewrites parts of a
request message before forwarding it.
Configuration Source
The Mediatrix 1204 must know the IP address and port number of the proxy server. You can assign these
information to the Mediatrix 1204 through a DHCP server or manually enter them yourself with the static
variables.
DHCP Configuration
Using the DHCP configuration assumes that you have properly set your DHCP server with the relevant
information. See
“Chapter 8 - IP Address and Network Configuration” on page 117 for more details.

To use DHCP-assigned information:
1. In the ipAddressConfig folder, locate the sipServerSelectConfigSource variable (under the
ipAddressConfigSipServer group).
This variable defines whether or not the Mediatrix 1204 must get its proxy server configuration
through a DHCP server.
2. Set the sipServerSelectConfigSource variable to dhcp .
You can query the proxy server’s IP address and port number assigned by the DHCP server in the
following read-only variables (under the
ipAddressStatusSipServer group of the ipAddressStatus
folder):
• sipHomeDomainProxyHost
• sipHomeDomainProxyPort
1. The Mediatrix 1204 does not use the Registrar server.
In the Unit Manager Network Administration Manual , refer to chapter Signalling Protocols Parameters , section
SIP Configuration Window .
Note:
When defining whether or not the Mediatrix 1204 must get its SIP server configuration through a
DHCP server, this is set for all the SIP servers. You cannot define a different configuration for each type of
server.
