11 Mar, 2026
Business VoIP phone systems, Microsoft Teams Voice and SIP trunking for companies across Liverpool — cloud telephony that costs less and does more.
2 hours 15 minutes by train from London Euston from our City of London office. We understand the Liverpool market and the communication needs of local businesses.
Bespoke VoIP and phone system packages designed for maritime and logistics, creative industries, tourism, life sciences, financial services, education businesses in Liverpool, aligned with your team size and budget.
Over two decades of IT and telecoms expertise. We've deployed hundreds of VoIP systems for businesses of every size and industry.
Three routes to modern business telephony. We recommend the right one based on how your team actually works — not what generates the biggest commission.
Full cloud phone system
A complete business phone system hosted in the cloud — no PBX hardware on your premises. Calls route through secure data centres with automatic failover, giving you enterprise-grade reliability with zero maintenance. Scales from 2 users to 2,000.
Calling inside Teams
Already using Microsoft Teams for chat and meetings? Add external calling directly inside Teams — one app for everything. Your team makes and receives calls from their existing Teams interface on desktop, mobile or IP handsets. No separate phone system needed.
IP connectivity for existing PBX
Already have a PBX you're happy with? SIP trunking connects it to the internet instead of traditional ISDN lines — slashing your call costs while adding disaster recovery and flexible call routing. Keep your existing investment, modernise the connection.
Liverpool is a major port city with a resurgent economy anchored by maritime trade, creative industries, and a thriving visitor economy. The Liverpool Waters and Knowledge Quarter developments are transforming the city's commercial landscape, while the Royal Albert Dock area has become a hub for digital and creative businesses. The city's strong cultural identity, UNESCO heritage, and two world-class universities drive innovation across multiple sectors.
Our team provides expert VoIP deployment and phone system support to maritime and logistics, creative industries, tourism, life sciences, financial services, education businesses across Liverpool. Based in the City of London, we are just 2 hours 15 minutes by train from london euston away, combining local knowledge with deep technical expertise in cloud telephony and unified communications.
We've partnered with Fidelity Group — an award-winning UK hosted telephony provider — to deliver enterprise-grade VoIP solutions to businesses of all sizes. Their Horizon platform and our IT expertise means you get a phone system that's properly configured, integrated and supported.
We don't sell phone systems — we solve communication problems. We start by understanding how your team actually works: who calls whom, how calls should be routed, what happens when someone's unavailable, and what integrations matter. Then we recommend the right solution for your Liverpool business.
A VoIP system is only as good as its setup. We configure call flows, auto-attendants, hunt groups, voicemail routing and user permissions properly from day one. We port your numbers, set up handsets and test everything end-to-end before go-live.
Unlike a telecoms company that disappears after installation, we're an IT company. Your phone system integrates with your network, your internet connection and your business applications — and we support all of it together, not in silos.
From first conversation to live phone system, we manage the entire process so the switch is seamless for your team.
We assess your current phone setup, call volumes, team structure and remote working requirements. We check your broadband is suitable for VoIP and recommend the right system — hosted VoIP, Teams Voice or SIP trunking.
We configure your entire phone system — call flows, auto-attendant menus, hunt groups, voicemail, user permissions and CRM integrations. We port your existing numbers so customers call the same number as before.
We pre-configure IP handsets, install softphone apps on laptops and mobiles, and provide hands-on training for your team. Everyone knows how to use the new system before we switch it on.
We manage the cutover to minimise disruption, monitor the system post-launch and provide ongoing technical support. Need a new user added, a call flow changed or a handset replaced? One call to us.
We're not a telecoms reseller that sells you a system and disappears. We're an IT company that understands how your phone system fits into your wider technology stack — your network, your internet connection, your Microsoft 365 environment and your CRM.
When we set up your VoIP system, we're thinking about call quality (is your broadband fast enough?), security (is your firewall configured for SIP traffic?), integration (does it connect to your CRM?) and user experience (can your team actually use it?). Most telecoms providers don't think about any of that.
Through our partnership with Fidelity Group, you get access to the Horizon hosted telephony platform — one of the UK's most reliable and feature-rich VoIP platforms. But unlike going direct, you also get our IT expertise layered on top — proper network configuration, QoS settings, firewall rules and integrated support.
Whether you need a straightforward hosted VoIP system for a small team or a full Microsoft Teams Voice deployment across multiple offices, we'll design the right solution, manage the migration and keep everything running.
We hold deep expertise across hosted VoIP, SIP trunking and Microsoft Teams Voice integration. Our team configures every system from scratch — no cookie-cutter templates, no shortcuts. Every call flow, hunt group and auto-attendant is built around how your business actually operates.
And because we work with businesses across London and the UK, we understand the connectivity landscape in Liverpool. We know which broadband providers deliver reliable service for VoIP and how to configure your network for crystal-clear call quality.

IT company first, telecoms provider second. That's why your phone system actually integrates with everything else.
We configure QoS, firewalls, VLANs and network settings properly — not just plug in phones and hope for the best. Your voice quality is our responsibility.
Phone system, internet connection and IT support — all managed by one team. No finger-pointing between providers when something goes wrong.
We don't just tick a box — we properly integrate your phone system with your CRM so screen pops, call logging and click-to-dial actually work reliably.
If Microsoft Teams Voice is all you need, we won't upsell you a full hosted PBX. We recommend based on what fits your business, not our margin.
We assess your broadband, configure QoS and test call quality before go-live. If your connection isn't good enough for VoIP, we'll fix that first — we do connectivity too.
VoIP fraud is real — hackers can run up thousands in international call charges overnight. Our systems include fraud detection and call barring to protect your business.
We manage the entire porting process — coordinating with carriers, scheduling the switchover and ensuring zero downtime. Your customers won't notice a thing.
Softphone apps on every device mean your team can make and receive calls from their business number whether they're in the office, at home or on the road.
Adding a new user takes minutes, not weeks. No engineer visits, no hardware orders, no waiting. Your phone system grows as fast as your business does.
Whether you're near Royal Albert Dock, Liverpool ONE or elsewhere in the city, Cloudswitched delivers the same high standard of VoIP deployment and phone system support that London businesses have trusted for over 20 years. We support maritime and logistics, creative industries, tourism, life sciences, financial services, education businesses with tailored telephony solutions that fit their specific team size, call volumes and integration requirements.

Got questions about business VoIP and phone systems? We've answered the most common ones below. If you need more detail, get in touch.
Traditional phone systems use a physical PBX box on your premises connected to ISDN lines. Hosted VoIP moves everything to the cloud — calls route through secure data centres over your internet connection. No hardware to maintain, lower costs, more features and works from anywhere.
Yes. We port your existing numbers to the new VoIP system so your customers, website and marketing materials don't need to change. The porting process typically takes 1-2 weeks and we manage it entirely on your behalf.
Hosted VoIP typically costs £8-£15 per user per month depending on features and call bundles. Microsoft Teams Voice is similar. Most businesses save 30-50% compared to traditional ISDN-based phone systems. We'll provide a clear quote based on your user count and requirements.
With a properly configured network and sufficient broadband, VoIP call quality is indistinguishable from a traditional landline — often better. We configure QoS settings to prioritise voice traffic and test call quality before go-live to ensure it meets business standards.
We configure failover routing so calls automatically redirect to mobile phones or an alternative number if your internet drops. For businesses where phones are critical, we can also set up a 4G/5G backup broadband connection through our connectivity service.
You'll need IP handsets (we supply and configure these) or softphone apps on your computers and mobile phones. If you're using Microsoft Teams Voice, you can use your existing Teams app — no additional hardware required unless you want desk handsets.
SIP trunking connects your existing on-premises PBX to the internet instead of traditional ISDN lines. It's the right choice if you have a PBX you're happy with but want lower call costs, disaster recovery and flexibility. If you don't have an existing PBX, hosted VoIP or Teams Voice is usually the better option.
Yes. Our hosted VoIP platform integrates with over 200 CRM and business applications including Salesforce, HubSpot, Zoho and Microsoft Dynamics. When a customer calls, their record pops up on screen automatically, and calls are logged against contacts — saving time and improving customer service.
Tell us about your current phone setup and we'll recommend the right solution — no obligation, no pressure. We'll assess your network, map your call flows and give you a clear, honest quote.
Whether you need a hosted VoIP system, Microsoft Teams Voice or SIP trunking for your existing PBX, our team is ready to design the right solution and manage the entire migration for your business.
