Explanation:
With the standard H.245 negotiation, the two endpoints need three round-trips before they agree
on the parameters of the audio/video channels (1. master/slave voting, 2. terminal capability set
exchange, and finally, 3. opening the logical channels). In certain situations and especially with
high-latency network links, this can last too long and users will notice the delay.
