Mediatrix 4100
Packages
The mgcpMIB supports five packages:
 Generic Media Package
 DTMF Package
 Line Package
 Extended Analog Line (XL) Package
 X-P Package
Setting the Default Package
You can set the default MGCP package of the Mediatrix 4100.
 To select the default package:
1. In the mgcpMIB, locate the mgcpDefaultPackage variable (in the mgcpMIBObjects group).
This variable defines the default package to use for all the endpoints. You have the choice between:
• Line Package
• DTMF Package
• Generic Media Package
The default value is Line Package.
2. Restart the Mediatrix 4100 so that the changes may take effect.
Dynamic Timeout Values
Although all the timeouts are provisioned in the MIB and currently set to the Basic MGCP Packages
suggestions (as defined in the following sections), the gateway controller may want to alter the timeout value
for some features. In this case, the timeout period (in milliseconds) is provided as a parameter to the signal
(RFC 2705bis-00).
Generic Media Package
The Generic Media package groups the events and signals that can be observed on several types of
endpoints, such as trunking gateways, access gateways or residential gateways.
 To set Generic Media package information:
1. In the mgcpMIB, locate the mgcpGenericMediaPackage group.
2. Set the ringback tone information.
The ringback tone (also referred to as ringing tone) advises the caller that a connection has been
made and that a calling signal is being applied to the called party or service point. See “Appendix D
- Country-Specific Parameters” on page 207 for more details on country-specific ringback tones.
Note: Currently, the Mediatrix 4100 does not NACK the modem tone request, but the modem tone request
is not yet supported.
