Cloud phone system for business

Your whole phone system — in the cloud, on every device.

Kooltel PBX gives your business a complete phone system: extensions, auto-attendants, AI answering, and apps for iPhone, Android and the web. No hardware to babysit, nothing to configure by hand.

Privately hosted · Secure by design · Works on the devices you already have

Everything a modern business needs

One system for calls, voicemail, and the smart stuff — managed from anywhere.

📞

Extensions & apps

Give every person an extension that rings their iPhone, Android and web app at once. Set up in seconds — scan a code and you're live.

🤖

Andrea auto answer

An AI voice agent that answers, routes and helps callers — 24/7, in your brand's voice.

🎛️

Auto-attendants & ring groups

Greet callers, press-to-route, hunt groups, queues and time-of-day rules — the full menu, without the complexity.

✉️

Voicemail to email

Every voicemail transcribed and delivered to your inbox, so nothing gets missed.

🔒

Private & secure

TLS everywhere, your data on our own infrastructure — not a reseller's. Security is the default, not an add-on.

🌎

Number portability

Keep your numbers. Add local, toll-free and new markets whenever you grow.
