How it works
From first conversation to live phone system, we manage the entire process so the switch is seamless for your team.
1
Discovery & Recommendation
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.
2
Configuration & Number Porting
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.
3
Handset Setup & Training
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.

Why Cloudswitched for VoIP?
IT company first, telecoms provider second. That's why your phone system actually integrates with everything else.
IT company, not a telecoms reseller
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.
One point of contact
Phone system, internet connection and IT support — all managed by one team. No finger-pointing between providers when something goes wrong.
CRM integration done right
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.
Right system, not the most expensive
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.
Network-first approach
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.
Fraud protection included
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.
Seamless number porting
We manage the entire porting process — coordinating with carriers, scheduling the switchover and ensuring zero downtime. Your customers won't notice a thing.
Hybrid & remote ready
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.
Scales instantly
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.
