What makes telecoms reliable

Three things make a business phone system reliable.

Phones that workFor years.

No phone system can survive a bad network.

Voice needs sufficient upload and download, with latency under 100 ms, so there is no jitter or delay on the call.

  • UniFi gatewayFirewall · voice routing · site-to-site VPN
  • Gigabit switching, structured cablingTested and certified from comms room to desk

How we build it StarOne switch at the centre. Every phone is one hop away, so calls arrive instantly.

Questions we are asked

Business telecoms, SIP and the switch-off, answered plainly.

What happens at the analogue switch-off on 31 January 2027?

Openreach retires the analogue (PSTN) and ISDN network. Anything still relying on a copper phone line stops working: traditional lines, alarm diallers, lift lines, door entry and older card terminals. For one line or a few, Voice Lite moves the line onto your broadband and your existing handsets plug into the router. For phone systems we move you to 3CX. Either way we port the numbers and switch over without downtime. Book a switch-off check.

Why 3CX rather than another phone system?

After auditioning most of the market over ten years we found 3CX evolves fastest and is the most reliable, integrated mid-market to enterprise system available in the UK. It was designed from the ground up to control call routing, run many IP handsets, live on a native mobile app and give you an interface you will actually use, with APIs and AI transcription built in. We have been a 3CX Platinum Partner since 2018.

Which carriers do you use for calls?

Gamma and Voiceflex. Both are carriers that UK infrastructure depends on, from blue-light services to hospitals and schools. We chose them on reliability and voice quality after a decade of testing, not on price.

Will it work for staff at home or on the road?

Yes. The 3CX app on iOS and Android and the desktop softphone make and take calls on your business numbers, transfer and route calls, and present the business professionally wherever the person is. It is light on bandwidth, so it performs on mobile data.

Can you connect more than one site?

Yes. Multi-site is designed in from the survey: resilient connectivity at each site, routers with proper firewalling and site-to-site VPN where needed, and one phone system across every location.

I only have one or two phone lines. What do I do about the switch-off?

Voice Lite. Your line moves onto a SIP service running over your broadband router, with no dependency on the retiring copper network. Your existing handsets plug into the router just as they plugged into the phone socket. We port your number and can come out and set it up.

What is a SIP trunk?

A SIP trunk is the internet connection that carries your calls to and from the public phone network, replacing ISDN lines. Ours run on Gamma and Voiceflex, with as many channels as you need and numbers kept or ported.

Do you install 3CX in Skipton, Leeds and Bradford?

Yes. We are based in Skipton and install and support 3CX phone systems across North and West Yorkshire, Lancashire and the UK, with remote deployment for sites further afield and in Ireland.

What does a telecoms project with L A Comms look like?

A Teams call to understand what you need, an indicative quote, then an engineer surveys the site to prove the design, including connectivity, switching and cabling. Deployment follows a plan you have seen, and the same team supports you afterwards.
