How to minimize the delay in voice calls.

In VoIPoFR when the link is full, there are big delays before the rings starts.

Qos used is LLQ and FRF12.

What is the procedure to priotitize(h225+h245)?

Re: How to minimize the delay in voice calls.

The h225 callset information is carried in tcp which is seen as data packet and also need to be classified as high priority.

To do this creat an access-list to catch tcp traffic to or from

port 1720. Then use CBWFQ and assign higher priority to this class than the rest of the data packets. This should be done

from source to destination on input output interfaces along the path to ensure faster call set-up time i.e faster delivery of call-setup info.
