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).
With SIP trunks, a single network can be maintained within the organization, rather than having both a voice and data network.  Internet bandwidth can be used more efficiently, streamlining expenses.  In addition, Moves, Adds and Changes can be completed without major wiring upgrades.  These benefits all lower costs for the business.
