What is the minimum number of TCP sessions needed to complete a H.323 call between two
Answer options:
A. 323 gateways using slow start?
B. 0
C. 1
D. 2
E. 3
F. 4
Answer correct:
C
Fast start allows for H323 media connections to be started at the beginning of a call. This is helpful for ringback scenarios, and also reduces the amount of time calls take to establish media. H245 is still negotiated later, but the actual media can be done earlier through H225 messages.
