How SIP Trunks Work

SIP Trunking acts as a virtual connection between an organisation and an Internet Telephony Service Provider (ITSP) either via lines that link SIP trunks to other IP traffic, or through the Internet via a Virtual Private Network (VPN).

During a call, you can have any of the following scenarios and more:

  • Be on a voice call with one other person
  • Have multiple people on a conference call
  • Run video calls

See the diagram on the right showing how calls flow from a SIP phone (VoIP) in a business to the internet. Nowadays, instead of routing voice calls over copper lines, SIP trunking sends them over data networks. In other words, the physical phone line is replaced with a virtual one which provide better quality voice solutions. The setup you’ll need to make the switch to SIP trunking includes the following:

  • NBN Internet connection
  • SIP-compatible PBX (Private Branch Exchange) box, also called IP PBX
  • VoIP phone, or VoIP adapters if you’ll use your existing traditional phones
