SIP Servers
The Mediatrix 4104 uses the following types of servers:

Registrar server

Proxy server

Outbound Proxy server

Presence Compositor server
This chapter describes how to configure the Mediatrix 4104 to properly use these servers.
You can also set these parameters via the web interface, as described in “SIP Servers Configuration” on
page 61 .
Registrar Server
The registrar server accepts REGISTER requests and places the information it receives in those requests into
the location service for the domain it handles.
Configuration Source
The Mediatrix 4104 must know the IP address and port number of the Registrar server. You can assign these
information to the Mediatrix 4104 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 141 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 4104 must get its registrar server configuration
through a DHCP server.
2. Set the sipServerSelectConfigSource variable to dhcp .
You can query the registrar 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):
• sipRegistrarHost
• sipRegistrarPort
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 4104 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.
