Detailed explanation-1: -UDP and TCP protocols are essential components of VoIP networks as they control how data gets exchanged over the Internet. However, VoIP environments also utilize the SIP (Session Initiation Protocol) to establish connections with other SIP devices (almost all devices use SIP for communication).
Detailed explanation-2: -Why UDP is used with VoIP? UDP provides a better experience for VoIP users as it allows them to enjoy a real-time and uninterrupted call without any delay. Errors such as packets losses have minor impact on the output audio and usually goes unnoticed.
Detailed explanation-3: -Signaling protocols for VoIP and Video-over-IP exist to determine the connection between the sending device and the receiving device. There are two types: session control, which incorporates SIP and H. 323 and media control, of which MGCP is a member.
