SIP Trunks

SIP Trunks – Telecom Networks

With the ISDN switch-off approaching, now is the perfect time to upgrade your phone system to SIP Trunks. At Telecom Networks, we provide fully managed SIP Trunks in Scotland and across the UK, giving businesses a modern, cost-effective way to make and receive calls. Our SIP solutions let you keep your existing PBX system while enjoying flexibility, scalability, and significant cost savings.

Our SIP Trunks are suitable for businesses of all sizes, from small companies looking to reduce costs to large enterprises needing scalable and resilient communications. They are particularly valuable for:

  • Businesses with multiple office locations.
  • Companies handling high call volumes.
  • Organisations supporting remote or hybrid working.
  • Any business wanting to modernise communications without replacing existing equipment.

SIP (Session Initiation Protocol) Trunks are virtual phone lines that connect your business phone system directly to the Public Switched Telephone Network (PSTN) using the internet. Unlike outdated ISDN lines, SIP Trunks use broadband or Ethernet connections to deliver crystal-clear, reliable voice calls. With the ability to support multiple channels at once, SIP is the smarter, future-ready choice for businesses of any size.

At Telecom Networks, we specialise in delivering robust and reliable SIP Trunking services across the UK. Our SIP solutions run on Gamma’s highly resilient, carrier-grade network, ensuring exceptional call quality and maximum uptime.
