VoIP Services
Cloud-hosted PBX with extension-to-extension dialling, auto-attendant, voicemail-to-email, and softphone clients — business telephony without the hardware.
Overview
A physical PBX on your premises means hardware that ages, maintenance contracts that renew, and capacity that is fixed at installation. VoIP Services replaces on-premise phone systems with cloud-hosted telephony — softphones, desk phones, and mobile clients registered to a cloud PBX that you manage through a web dashboard. Extensions, trunks, auto attendants, voicemail, and call queues are configured online, not on a switch in your comms room.
Clevertek scopes every engagement to your environment — capacity, sites, compliance and support model — so you get a tailored plan rather than a fixed SKU. Pricing is quote-only, and our solutions architects will work through your requirements before any proposal.
Our approach
We deploy and manage cloud-hosted VoIP telephony for businesses replacing or augmenting existing PBX systems. We set up the cloud PBX platform, provision user extensions, configure auto-attendants and call queues, deploy desk phones and softphone clients, and integrate with your existing SIP trunks. Features are activated through a self-service portal — adding a user, changing a greeting, or creating a hunt group takes minutes without touching any hardware.
Why work with us
Cloud-hosted PBX
No PBX hardware on your premises — extensions, trunks, and features managed through a web portal. Hardware is a phone, not a server.
Softphone and mobile clients
Users make and receive calls from desktop softphones and mobile apps — same extension, same features, as if sitting at their desk phone, anywhere with internet.
Auto-attendant and call queues
Professional auto-attendant greeting with department routing. Call queues with music-on-hold, estimated wait time, and priority queuing for VIP callers.
Extension-to-extension free calling
Internal calls between extensions are free — no per-call charges, no trunk utilisation for inter-office calls, regardless of physical location.
SIP trunk integration
Connect your existing or new SIP trunks to the cloud PBX for DDI numbers and outbound calling — one voice platform, multiple trunk providers.
Scalable from 5 to 5,000 users
Add extensions in minutes with no hardware installation. Capacity scales elastically — no forklift upgrade when you grow from 20 to 200 users.
Key benefits
What this solution delivers for your business.
Eliminate PBX hardware and maintenance
No PBX chassis, no voice gateway, no maintenance contracts. The phone system is a service, not an asset on the depreciation schedule.
Remote and hybrid work ready
Users make and receive calls from anywhere using the same extension — softphone on laptop, mobile app, or desk phone at the office. No VPN, no forwarding codes.
Add users in minutes
New hire joins? Create an extension through the portal, assign a number, and provision a softphone — done. No cabling, no PBX programming, no engineer visit.
Predictable per-user pricing
Fixed monthly cost per extension includes all features — auto-attendant, call queues, voicemail, conferencing, and softphone clients. No per-minute surprises.
Enterprise features without enterprise complexity
Auto attendants, ring groups, music-on-hold, call recording, and voicemail-to-email — features that used to require expensive PBX licensing are included.

Questions buyers actually ask
Do I need new phones?
Not necessarily. Many existing SIP-compatible desk phones work with our platform. For phones that are not compatible, we supply and configure SIP handsets as part of onboarding.
What happens if the internet goes down?
Calls can be forwarded to mobile phones automatically when the platform detects your internet is down. SMS and mobile app calling keep essential telephony working.
Can I keep my existing numbers?
Yes. We port existing DDI numbers to the SIP trunk provisioned for your cloud PBX. Number porting is coordinated with your current carrier.
Is call quality better than my current system?
VoIP call quality depends on your internet connection. We recommend a dedicated DIA circuit for voice with QoS configured. With the right underlay, voice quality matches or exceeds ISDN.
