Gamma Migration in London
Migrating London organisations off traditional lines onto Gamma, where the things that break are rarely the telephones. Lift emergency phones, alarm panels, door entry, card terminals and the fax the accounts team still receives orders on are all sitting on analogue lines nobody counted as part of the phone system.
Why this comes up
The problem
The phones moved on schedule and the lift emergency line and the alarm panel stopped working the same weekend.
What you get
What we deliver
- Every analogue line traced to what is actually connected at the far end
- Life safety services identified first — lifts, alarms, emergency call points
- Replacement route decided per device, since some cannot simply move to internet calling
- Third parties engaged early, as alarm and lift providers set their own timescales
- Card terminals and similar equipment confirmed with the provider before switching
- Cutover sequenced so critical services are proven before the old line is ceased

Gamma Migration in London — common questions
- Why are lift and alarm lines the priority?
- Because failure has consequences beyond inconvenience. A lift emergency telephone that stops working leaves somebody trapped with no way to call for help, and an alarm panel that cannot signal fails silently — neither announces itself until the moment it is needed.
- Can these devices just move to the new service?
- Some can with an adapter and some genuinely cannot. Equipment designed for the analogue network behaves unpredictably over internet calling, and for lifts and alarms the correct answer is frequently a dedicated replacement solution specified by the equipment provider rather than an adapter.
- How do we find every line?
- By tracing rather than by asking. Billing shows what you pay for and not what is attached, so the exercise involves walking the site, checking what each socket serves and reconciling the result with the invoice — which routinely finds lines nobody could account for.
- How much notice do third parties need?
- More than the phone migration does. Alarm monitoring and lift maintenance providers schedule their own engineers, sometimes weeks out, and their work has to complete before the line is ceased — so they are the constraint on the timetable rather than a task to arrange afterwards.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
