If your firm is looking for a business phone system in London that clients and investors can rely on from the first call of the morning to the last, then give us a ring. We have decades of experience in business phones, and we will make sure your callers are met with a polished, friendly welcome.
The sound quality is excellent, and callers are directed to wherever you have requested them to be routed. Your team can answer at a desk handset, inside Microsoft Teams, on our app or on a laptop, on Cheapside, in a Shoreditch studio or on the Tube home.
Our friendly UK team will gladly help on 020 8159 1900.
London firms seldom switch phone supplier, and with clients and investors ringing all day, the move must go unnoticed. A capable VoIP provider in London keeps your 020 numbers untouched and your team on the phones throughout.
VoIP routes your calls through your internet connection and lets the analogue line go, and you might hear it called cloud calling or a hosted PBX. People can answer in the office, at a coworking desk or at home.
Ask about free porting, phones that turn up configured, call recording that suits your sector’s rules and who picks up the support line. Blake Telecom covers all four, with the engineers who built your setup answering, which is why firms pick us as their VoIP provider in London.

We look after insurers near Lime Street, law firms in Holborn, agencies in Clerkenwell and property managers in Wimbledon, and each business phone system in London is planned around the people answering it, never a fixed bundle.
We start by asking who takes calls, which office or coworking space they use and what software they work in. Picking between phone systems in London should be straightforward, and we always explain things without jargon.
Offices in Croydon, Stratford, Wimbledon and Harrow can join one business phone system in London. A caller who rings Cheapside can be put through to Croydon within seconds.
The features London teams rely on most are listed below.
An 020 number shows people you are a London business. Once the port is approved, we move it to our hosted service on the date you choose.
Porting your 020 numbers across is free of charge.
Once it has moved, a call can ring someone’s handset, laptop and mobile in one go, and your staff still show the London number when they ring out.
A partner at a meeting in New York and an analyst working from home in Bromley can both answer your 020 number on the app.
Clients you ring see the London office number, never somebody’s own mobile.
VoIP, short for Voice over Internet Protocol, turns speech into data and sends it over your broadband in place of a copper line.
The audio is crisp, which is why VoIP phone systems in London now carry calls for brokers, agencies and practices. Our VoIP guide explains the basics.
UCaaS, or Unified Communications as a Service, keeps calls, video, chat and the staff list in a single app. Have a look at the UCaaS page for the details.
Imagine an investor in Edinburgh calling the 020 number on your business phone system in London about a funding round.
Your receptionist can message the partner, pass the call to the deal team or open a video meeting in the same app, and an AI summary records what your team agreed to send.
CCaaS (Contact Centre as a Service) is made for customer service floors, booking desks and claims teams that are on the phone all day.
You get queues, skill-based routing, live wallboards and scores for each call, and our UCaaS and CCaaS solutions overview looks at each tool in turn.

A friendly recorded greeting lets callers choose sales, support or accounts.
At busy times, callers hold in turn, and you set the music, the longest wait and a greeting for nights and weekends.
Your routing rules send each call to a named colleague, a whole team or a different office, depending on the time and who has logged in.
Staff commuting in from Surrey or Essex answer your business number in our app on the train or at home, and your staff can also have business mobiles from us.
Recordings are useful for coaching, quality checks and complaints. Each London recording is retained in warm storage for a month, with an option for 180 days, and older files can go into a ten-year cold archive.
Link a supported CRM, and a London client’s history is in front of you before you say hello.
If your firm already works in Microsoft Teams, direct routing puts your 020 calls right inside it.
For changes or a helping hand, just call 020 8159 1900 and talk to a friendly UK engineer.

Insurers, shops, travel firms and housing groups in London take huge numbers of calls. Once your own lines get that busy, we can switch on a live wallboard and queues on the account you already use.
With the wallboard, supervisors can follow the queue, the longest wait and the answer rate since opening, next to a list of free agents. Our contact centre solutions page shows it in more depth.

London firms asking about telephone systems in London usually give three reasons for switching.
Hybrid working. An associate working from home in Walthamstow answers the office number, with the firm’s contacts and recent calls right there on a laptop.
Business continuity. If your office loses power or internet, your calls still get answered. They are diverted to mobiles or another branch, and you are not paying for a backup system.
Voicemail to email. A missed call is emailed to you as a sound clip, ready to play between meetings.

If you need us, ring 020 8159 1900 and reach the engineers who configured your London system.
Most faults are fixed remotely, and we will arrange a site visit when one is genuinely needed.
Since 2004, we have been helping businesses move off copper and onto cloud calling, and we can supply your office with business broadband and leased lines too.
The analogue phone network closes nationwide on 31 January 2027. Period buildings in particular still run alarm diallers, lift lines, door entry and card terminals over copper, and it is worth listing them well before the deadline.
Because broadband carries it, a cloud business phone system in London gives you routing, voicemail and apps on launch day.
We test your connection, flag any device still on copper and plan the switch around your working day. Eligible 020 numbers normally move with you, and the suppliers of your alarms and card terminals will explain their part.
