[cisco-voip] QoS for Gatekeeper RRQs

[Andre Beck]

Hi,

I'm installing a network of CCMEs which register themselves at a
central H.323 gatekeeper (IOS). I've got every H.323 traffic to
bear the intentional DSCP either by default or using "ip qos"
in the dialpeer blocks. I haven't found a way to control the
DSCP or IP precedence used when the gateway talks to the gatekeeper,
though. According to precedence accounting these RRQs are done
with a precedence of 0 and consequently I lose registration with
the gatekeeper when firing heavy traffic on the installation (QoS
preserves the priority of voice and other signaling packets quite
nicely, but the default traffic class drops packets, including
the RRQ ping-pong).

How do I set the DSCP used by gateway/gatekeeper functions that
are not related to dialpeers?

TIA,
Andre.
