Voice over Internet Protocol (VoIP) is a technology that allows voice communication to be transmitted over the internet instead of traditional telephone lines. It is a cost-effective solution for businesses and individuals looking to communicate globally without incurring high call charges. Session Initiation Protocol (SIP) is a protocol used to initiate, maintain, and terminate real-time communication sessions, including VoIP calls.
What is VoIP? VoIP is a method of transmitting voice calls over the internet instead of traditional telephone lines. This technology converts the voice signals into digital packets and transmits them over the internet. It allows for a more cost-effective and efficient way of communication, especially for long-distance or international calls.
VoIP has become increasingly popular in recent years due to its ability to provide additional features such as call forwarding, conference calling, and voicemail at a lower cost than traditional phone systems. Additionally, VoIP can be easily integrated with other communication tools such as instant messaging and email.
What is SIP? Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating real-time communication sessions, including VoIP calls. It is an open standard protocol that can be used to initiate multimedia communication sessions such as voice, video, and messaging.
SIP works by establishing a session between two or more endpoints, such as phones or computers, and negotiating the parameters of the session such as the media type, codec, and transport protocol. SIP also handles call routing and allows for features such as call forwarding and call transfer.
SIP is widely used in the telecommunications industry and is supported by most VoIP service providers. It is a flexible and scalable protocol that can be easily customized to meet the needs of different applications.
