You can configure default values for various H.248 properties. The VPG uses these values unless the PGC overrides them with a PGCP command. You can set default values for properties defined in the H.248 Base Root package and the H.248 Segmentation package.
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 VPG and PGC send and receive provisional responses to H.248 commands.
The segmentation package is defined in annex E.14 of the Gateway control protocol v3, ITU T Recommendation H.248.1, September 2005. The properties in this package affect the limits used when long H.248 replies are segmented into several H.248 messages.
To configure default values for base root and segmentation properties, include the default-h248-properties statement at the [edit services pgcp gateway gateway-name] hierarchy level:
- [edit services pgcp gateway gateway-name h248-properties]
-
