SIP Trunking

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.

How Your Business Can Benefit from SIP Trunking

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.

Advantages to SIP trunking include

  • Reliably combines video, voice and data in one line, which eliminates the need to separate media modes.
  • Reduces overall costs of transmitting multimedia services.
  • Companies can purchase dozens of channels or a few channels and have unlimited minutes to use on these channels.
  • Eliminates physical connections to telephone companies - no wiring, circuit boxes or bulky hardware to maintain for a connection to a PSTN.
  • DIDs (Direct Inward Dialing numbers) are much less expensive when bought through SIP trunking because there are no additional charges that come with using a phone company.
  • With SIP trunking, businesses enjoy significantly better reliability of service due to redundancy, or the ability of SIP trunking providers to reroute services if system emergencies occur.
