NetMeeting 

(H.323)

A multimedia communications product from Microsoft that enables groups to 

teleconference and videoconference over the Internet. NetMeeting supports VoIP, 

text chat sessions, a whiteboard, and file transfers and application sharing. 
NetMeeting uses H.323. H.323 is a standard teleconferencing protocol suite that 

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

and multipoint communication between client computers over a packet-based 

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

VoIP (SIP)

Sending voice signals over the Internet is called Voice over IP or VoIP. Session 

Initiated Protocol  (SIP) is an internationally recognized standard for implementing 

VoIP. SIP is an application-layer control (signaling) protocol that handles the 

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.

Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP, but 

uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control 

Protocol).
