What is Sip Trunking?

SIP – Session Initiation Protocol, a popular telephony protocol that initiates calls over the internet and is primarily used to manage multimedia communications, such as voice and video calls. SIP establishes and terminates the connection for a phone call, controls the transmission of data, and is what allows services like Skype and Facebook Messenger to offer free calls anywhere in the world.
