Chapter 9 - SIP Servers Presence Compositor Server
142 Mediatrix 1204
Presence Compositor Server
The Presence Compositor server is a User Agent Server (UAS) that processes PUBLISH requests and is
responsible for compositing event state into a complete, composite event state of a resource for a presentity.
The presence Compositor is enabled if the IP address is valid (i.e., not 0.0.0.0). The default static value in the
MIB is 0.0.0.0.
Configuration Source
The Mediatrix 1204 must know the IP address and port number of the Presence Compositor 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 Presence Compositor server
configuration through a DHCP server.
2. Set the sipServerSelectConfigSource variable to dhcp .
You can query the Presence Compositor 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):
• sipPresenceCompositorHost
• sipPresenceCompositorPort
3. Set how you want to define the Presence Compositor server information in the DHCP server.
Standards Supported • RFC 3863 – Presence Information Data Format (PIDF)
• RFC 3903 – Session Initiation Protocol (SIP) Extension for
Event State Publication
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.
Table 89: Presence Compositor Server DHCP Information
To use a... Set...
vendor specific code The sipPresenceCompositorDhcpSiteSpecificCode variable (under
the ipAddressConfigSipServer group) to 0 . Set the proxy server IP
address in the DHCP server inside the vendor specific sub-option

site specific code The sipPresenceCompositorDhcpSiteSpecificCode variable (under
the ipAddressConfigSipServer group) to any value between 128 and
254. Set the Presence Compositor server IP address in the DHCP
server inside the site specific option you have chosen (it must match
the value of the
sipPresenceCompositorDhcpSiteSpecificCode
variable in the unit's configuration).
