Configuring H.248 Base Root Properties

You can configure default, minimum, and maximum values for properties defined in the H.248 base root package. The virtual BGF uses the default values unless the gateway controller overrides them with an H.248 command. You can configure maximum and minimum values to limit the range of values accepted from the gateway controller. In general, we recommend you use the values that are configured on the router by default.

The base root package is defined in annex E.2 of the Gateway control protocol v3, ITU-T Recommendation H.248.1, September 2005. The properties in this package mostly affect the timers used when the virtual BGF and gateway controller send and receive provisional responses to H.248 commands.

Step-by-Step Procedure

To configure H.248 timers for the PGCP connection between the virtual BGF and the gateway controller:

Access the configuration of the H.248 base root properties.
