What is cloud VoIP?
Cloud VoIP is a business phone system hosted entirely in a provider’s cloud. Calls travel over the internet, and there is no on-premise PBX hardware to buy or maintain; users connect via desk phones, apps, or softphones. The move to cloud voice is nearly complete in developed markets: Panterra reports over 60% of companies have migrated, and cloud softphones now hold over 65% of the market.
How does cloud VoIP differ from on-premise?
| Cloud VoIP | On-premise | |
|---|---|---|
| Hardware | None to own | You buy and maintain it |
| Cost | Per user, monthly | Upfront plus maintenance |
| Updates | Provider handles | Your responsibility |
| Scaling | Instant | Provision hardware |
How much does cloud VoIP cost?
Cloud VoIP is billed per user per month, and the savings over legacy lines are consistent: 30% to 50% lower communication costs, up to 68% on usage-based plans. There is no upfront hardware investment, and features like call routing, voicemail-to-email, and mobile apps are included. The predictable per-user fee is a large part of why cloud VoIP became the default choice.
What do you need for reliable cloud VoIP?
A stable network. Voice is real-time and sensitive to latency and jitter, so adequate bandwidth and quality-of-service prioritization for voice traffic keep calls clear. Plan a failover for internet outages. An MSP already managing your network can run cloud VoIP alongside it, giving you one accountable vendor for connectivity and voice (Kixie tracks VoIP adoption).
