Configuring Rate Limiting for the BGF

You can configure rate limiting for voice calls on the virtual BGF by setting default, minimum, and maximum values for properties defined in the H.248 traffic management 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 if you want to limit the range of values accepted from the gateway controller. Parameters for the RTCP stream take effect only when the gate is an RTP/RTCP gate. You can configure peak and sustained data rates for the RTCP stream as a set rate or as a percentage of the corresponding RTP data rate.

The traffic management package is defined in Annex C of Gateway control protocol v3, ITU-T Recommendation H.248.53, — June 2008.
