    A reading of RFC 3550 should make it clear once basic differences between TCP and UDP (and similar) are understood. Just diagram the flows, especially when three or more end-points are participating.

    Note, e.g., section '10. Congestion Control' of the RFC.

    But also note section '13.  RTP Profiles and Payload Format Specifications', in particular its reference to section '11. RTP over Network and Transport Protocols'.

    The VoIP networks combine both voice and data communications. The TCP is not adequate for VoIP by adding some additional new protocols for the applications such as voice and video.
