SIP trunks are quickly changing the way businesses communicate by providing additional features not found with traditional phone service, while adding flexibility and substantial cost savings. SIP trunking allows a business to replace traditional fixed POTS lines with connectivity via the provider through the internet, and the customer’s PBX/IP PBX. How does it work? Short answer: SIP trunking routes calls from an IP PBX over a network secure MPLS path using Session Initiation Protocol, delivering IP communication.
