text chat sessions, a whiteboard, file transfers and application sharing.

provides audio, data and video conferencing. It allows for real-time point-to-point

network that does not provide a guaranteed quality of service.
H.323 is transported primarily over TCP, using the default port number 1720.

setting up, altering and tearing down of voice and multimedia sessions over the
Internet.
SIP is transported primarily over UDP but can also be transported over TCP,
using the default port number 5060.
