What is SIP Trunking?

Session Initiation Protocol (SIP) trunking is the use of voice over IP (VoIP) to facilitate the connection of a private branch exchange (PBX) to the Internet. This means that the internet replaces the conventional telephone trunk.

With SIP Trunking you can;

  • Initiate and receive local calls
  • Initiate and receive long-distance calls
  • Make emergency calls (911)
  • Access directory assistance
  • Use fixed and mobile telephone sets
  • Employ e-mail and texting
  • Browse the Web
