SIP trunk providers are communication service providers that utilize the Session Initiation Protocol (SIP) to provide voice and multimedia sessions over the Internet. They can be used to interconnect an organization’s VoIP infrastructure with the public switched telephone network, allowing businesses to make use of their existing VoIP systems while also taking advantage of external telephony services. SIP trunking is seen as a cost-effective way of providing reliable voice and data services for businesses.
