Sip Trunking

Our farewell to the PSTN ISDN – take the decision, of the transition to VoIP trunks with GoSiP

Deliver enhanced voice services

SIP Trunking is a service that provides VOIP or Voice over Internet Protocol. In other words, it is a form of communicating by transmitting telephone calls over the Internet. As the major telephone network operators look to phase out their ISDN services, more organisations are migrating across to SIP Trunks to deliver enhanced voice services into their organisation.

Benefits of SIP Trunking

  • Lower monthly Line & DID Rental – The monthly fee to have a number of lines installed at your office drops significantly with SIP Trunks. And DIDs cost a lot less.
  • Lower call charges – There are many SIP Trunk providers and competition has driven down call charges significantly. Some SIP Trunks even come with unlimited calling and you can save on international call charges, too.
  • Better customer service – Provide better customer service by adding more geographical and international numbers. Quickly and easily add numbers to your SIP Trunk and terminate them on your IP PBX – you can give customers more options to dial in at a significantly lower cost, even long distance. Customers can contact you more easily and sales will increase.
  • Move offices and keep the same number – SIP Trunks are not bound to a location, so it’s easy to move offices without having to change your stationary or inform your customers. There is no longer any need to pay to forward phone calls to the new offices.
  • Eliminate VoIP Gateways – SIP Trunks will eliminate the need to buy and manage VoIP Gateways. All phone calls come in via IP. No extra conversion often means better quality too.
  • Leverage a modern IP PBX – Modern IP PBX / Unified Communications solutions will give customers increased productivity, mobility and boost sales. Connecting an IP PBX to SIP Trunks is much easier than via the PSTN. You can go on-premise or hosted, the choice is yours.
  • Flexibility – It is easy to add channels to your SIP Trunk to cope with increased calls. A simple phone call will allow you to add channels, and often this can be done immediately. Compare that to the delay in having additional lines installed and then having to upgrade your old PBX to handle more lines!
  • Correct number of channels – With SIP Trunks, you can easily choose the correct number of channels that you need.
