SIP Provider

SIP Trunking is a term applied to the services offered by a SIP Provider or LECs (Local Exchange Carriers), ILECs (Independent Local Exchange Carriers), CLECs (Competitive Local Exchange Carriers) and ITSPs (Internet Telephony Service Providers) to terminate Voice over IP (VoIP) calls to the Public Switched Telephone Network (PSTN).

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 (as compared to 23 channel increments for a PRI). Your company will reduce costs using Voice SIP Trunks versus traditional TDM lines.

Here’s a hypothetical example of how SIP Trunking works: A Los Angeles-based sales representative places a long distance call to a client based in New York City using a dialing prefix and the local-area phone number. The call either originates as an IP call or is converted to one before it leaves the office and then travels the majority of the way over the IP network of the service provider, then drops back down to the PSTN once it reaches its termination point. Since a sizable portion of the call traveled over the IP network at no additional cost rather than on the PSTN, the service provider can (and does) charge a mere fraction of what the traditional fee would be without the IP connection.

With these facts in mind, there is no question that SIP Trunking offers compelling advantages for businesses large and small.
