SIP Trunking: How can it make you a hero?

SIP Trunking is a standards based replacement for traditional ISDN. It connects your PBX to the PSTN via broadband, Ethernet or private circuit into our national network.  Compared to ISDN, SIP trunking is less costly per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and it delivers extremely robust business continuity.
Organisations using SIP Trunks can expect to:
  • Save money on call costs and line rental (it can save up to 50% on line rentals and 25% or more on call costs)
  • Have low-cost or free internal calls and great features
  • Scale up as and when required
  • Have built-in business continuity
We recommend SIP trunks that are built for voice environments such as Skype for Business (formally Microsoft Lync).  The SIP Trunks we recommend are integration tested and approved to interoperate with Microsoft’s Unified Communications solution, allowing you to directly connect to the Skype for Business platform to make external calls.
