SIP trunks

What is a SIP Trunk?

A Voice Over Internet (VoIP) phone line which connects users via a service provider's data networks. Instead of a physical wire, a SIP Trunk is your 'virtual' wire through your phone system back to your provider's network.


Why would I use a SIP Trunk?

  • SIP Trunks will replace ISDN technology in 2025, so you're future-proofing yourself.
  • Calls are up to 50% cheaper when compared to ISDN calls.
  • This is a scaleable solution – instead of having to buy a set number of fixed ISDN lines you can simply add more connections without any physical re-installation.
  • It's a great solution for multi-site organisations – people can be connected company-wide without being physically connected.
  • Simpler business continuity planning – in the event of a disaster SIP Trunks can be re-rerouted anywhere with internet connection, to keep you talking!
  • You can port existing numbers and even use numbers that don't necessarily correlate to your physical location.


Digital and IP Handsets

Design Communications offer a wide range of IP and Digital handsets.

All handsets have been ergonomically designed, are easy to use and give users the appropriate features and access levels for their individual needs.
