Dynamic H.245 flows

I'm in the midst of creating a QoS policy for a customer and I'm struggling with classifying traffic--specifically H.245 and the dynamic tcp ports it uses. I can recognize the audio and video utilizing a protocol match on rtp, however it doesn't appear as though there is a similar solution to my H.245 issue. Is there a way to recognize dynamic H.245 flows using a match protocol, etc? I'd much prefer a specific match rather than an access-class matching a range of ports between 1024 and 65535! Any help would certainly be appreciated.

Re: Dynamic H.245 flows

If you configure fast-start (H245 tunelling) at the endpoint sides (gateways, IP phones...), then the H245 traffic will be "tunelled" inside the call signalling (H225) and thus pass through the tcp/1720 port.

All the H323 devices must support fast-start (this feature was implemented in H323 v2, long time ego).
