SIP Trunking 
SIP Trunking is a term applied to the services offered by carriers and service providers to terminate Voice over IP (VoIP) calls to the Public Switched Telephone Network.
SIP trunking allows enterprises and small businesses to eliminate a PSTN gateway at their site and outsource that function to a carrier. It is typically a lower-cost alternative to Primary Rate Interfaces (PRIs) because SIP trunks can be purchased in single-trunk increments.
The development of SIP Trunking, commonly known as Voice Over Internet Protocol (VOIP), is revolutionizing the way we communicate. For business, the benefits are endless. In particular, Easy SYstem’s SIP trunking services provide the opportunity to incorporate a range of products that can streamline your business operations.
