Platform, Security & Integrations / Deployment Options

Hosted / Software Edition

Instead of dedicated hardware at your office, the phone system can run entirely as software — deployed on a cloud server or on your own server/virtualization platform — and scales up or down on demand as your business changes, without needing new physical equipment.

What’s the main advantage over a physical appliance?

Flexibility and speed of scaling. Adding capacity — more extensions, more concurrent calls — is a configuration change rather than a hardware purchase and install, which makes it a strong fit for businesses that are growing, seasonal, or spread across multiple locations.

Where does it actually run?

It can be deployed on major public cloud platforms or on your own on-premises virtualization infrastructure if you’d rather keep it in-house — either way, it’s the same software, just hosted differently.

How much can it scale?

Software Edition deployments are built to scale well beyond what appliance hardware supports — from a small team up to thousands of extensions and hundreds of concurrent calls — so it’s a good fit even for larger, more complex organizations.

Is it less reliable than a physical box sitting in my office?

No — if anything, a properly managed hosted deployment typically has stronger redundancy options, including High Availability & Hot Standby and Disaster Recovery, than a single on-site box would have on its own.

Can I mix this with an on-site appliance?

Yes — see Hybrid Deployment for how the two models can work together, for example keeping some hardware on-site while running additional capacity or disaster recovery in the cloud.
