What is SIP Trunking?

  SIP trunking represents the digital evolution of traditional analog phone lines.Unlike PSTN,ISDN BRI,or T1 lines that depend on physical connections,SIP trunking converts voice signals into digital packets,which are then seamlessly transmitted using Voice over Internet Protocol(VoIP)technology.

  By leveraging the Session Initiation Protocol(SIP),businesses can effectively integrate their voice and data networks,leading to substantial cost savings and more streamlined operations.This service is typically offered by Internet Telephony Service Providers(ITSPs)and frequently interfaces with SIP-enabled business phone systems(PBX)to facilitate daily audio and video calling functions.
