Cloud PBX vs On-Premises PBX

Cloud PBX moves call control to a provider’s data centre; on-prem keeps a physical or virtual PBX in your office. The right choice blends capex, resilience, compliance and how much you trust your uplink.

Opex vs capex

Cloud shifts spend to per-seat monthly fees with faster feature releases. On-prem amortises licences and appliances across years — attractive if you already operate a virtualised stack.

Survivability

Cloud survives local power cuts if handsets failover to mobile apps — but needs clean internet. On-prem can take PSTN-era gateways but still needs LTE backup for SIP trunks.

Integrations

Microsoft Teams, CRM screen-pops and call recording rules differ by vendor. Validate compliance retention before you commit — export paths matter for regulated sectors.

Number ownership
