IP phone system price: cloud or on-premises

In the cloud, you pay a monthly fee per extension. You do not buy a server or manage licences; updates and maintenance are included, and capacity follows the team. The bill combines the monthly fee, call traffic, IP handsets (bought once) and installation. It is the natural choice up to around fifty extensions, for multi-site companies or those with many remote staff.

In the company's own rack, you buy equipment and licences, install them locally and then pay only call traffic and an annual maintenance contract. After three or four years it usually comes in below the cloud — and it is unavoidable where there are isolation requirements, integration with internal systems or an old PBX to reuse.

The detailed analysis is in cloud vs on-premises PBX: decision criteria.

• Number of extensions Sets the cloud monthly fee and on-premises licensing.
• Handsets A basic phone and a reception console with a screen and BLF keys are priced very differently.
• Simultaneous channels Too many wastes money; too few gives callers an engaged tone.
• Recording Licences, disk space and GDPR obligations.
• IVR and queues Voice menus, schedules and overflows increase licensing.
• CRM integration Caller identification, automatic logging, click-to-call.
• Number porting A one-off charge that keeps the number printed on your business cards.
• Network infrastructure Without QoS, voice fails; an honest quotation may have to include the network.

Because VoIP is real-time traffic. Without priority configured on the switches and firewall, without a stable connection and, ideally, without redundancy, the new PBX inherits the old one's drop-outs. On a well-sized managed network, adjusting the configuration is enough; on an ageing, unmanaged network, it has to be fixed first. DataRoad always assesses the network before proposing telephony.

1. Number porting — without it, you lose the number your customers know.
2. Numbering plan and call routing — schedules, public holidays, groups, divert to mobile. This is where it is decided whether the PBX helps or irritates.
3. Network preparation — without QoS, nothing improves.
4. Post-installation support — who fixes it when an extension goes silent at 9 a.m. on a Monday.

With three answers: number of extensions, simultaneous calls and the features genuinely needed. If the network raises doubts, we audit it first — we would rather recommend fixing the network than install a system doomed to fail. The PBX is then managed under the IT Unlimited contract, by the same team that runs the network.
