Outbound Proxy Server Reference Manual (SIP Version)
Mediatrix 4104 167
Configuration Source
The Mediatrix 4104 must know the IP address and port number of the outbound proxy. 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 ask for its outbound proxy settings
through a DHCP server.
2. Set the sipServerSelectConfigSource variable to dhcp .
You can query the outbound proxy’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):
• sipOutboundProxyHost
• sipOutboundProxyPort
3. Set how you want to define the outbound proxy server information in the DHCP server.
Static Configuration
Use the static configuration if you are not using a DHCP server or if you want to bypass it.

To use static information:
1. In the ipAddressConfig folder, locate the sipServerSelectConfigSource variable (under the
ipAddressConfigSipServer group).
This variable defines whether or not the Mediatrix 4104 must ask for its outbound proxy settings
through a DHCP server.
2. Set the sipServerSelectConfigSource variable to static .
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.
Table 103: Outbound Proxy Server DHCP Information
To use a... Set...
vendor specific code The sipOutboundProxyDhcpSiteSpecificCode variable (under the

server IP address in the DHCP server inside the vendor specific sub-
option 205 (hexadecimal 0xCD).
site specific code The sipOutboundProxyDhcpSiteSpecificCode variable (under the
ipAddressConfigSipServer group) to any value between 128 and 254.
Set the outbound proxy server IP address in the DHCP server inside
the site specific option you have chosen (it must match the value of
the
sipOutboundProxyDhcpSiteSpecificCode variable in the unit's
configuration).
