Session Initiation Protocol (SIP) trunking uses VoIP to facilitate connections of PBX (private branch exchanges) to the Internet. Essentially, SIP trunking allows the Internet to replace conventional telephone trunks (or lines carrying multiple signals simultaneously to connect switching centers within a communication system) so that businesses can communicate with mobile and fixed telephone subscribers all over the world.
SIP providers are also called Internet Telephony Service Providers (ITSP) who provide PSTN services based on a channelized or per minute pricing model.
Initially, your company needs a gateway that acts as an interface between the ITSP and PBX and a PBX capable of connecting to all end users.
