What a business phone system is

A business phone system is the set of numbers, users and rules that a company uses to make and receive calls. phone.systems™ runs the whole system in the cloud: numbers, users, extensions, call flows, calling apps, call recording and call history are managed in one account, with phone numbers from the same platform.

How the parts connect

  1. Numbers are added to the account — local, national, mobile, toll-free, shared cost or UIFN in 93 countries, third-party numbers, or numbers from your own carrier.
  2. Users get an internal number and contact methods: the phone.systems™ app, a SIP account, SIP forwarding or PSTN forwarding.
  3. Time schedules define working days, hours and holidays, per company or per user.
  4. Each number is connected to a call flow that routes calls through voice menus, time routers, ring groups and queues.
  5. Team members answer in the app or on a SIP device. Every call appears in call history, and can be recorded and analysed with AI call insights.

Where it fits

A cloud business phone system fits companies that want one phone setup for the whole team without on-site hardware — a small business, a remote team or a business with several locations.

Frequently asked questions

What is a business phone system?

A business phone system gives a company shared phone numbers, internal extensions and rules for where incoming calls go. A cloud business phone system runs these in an online service instead of on-site hardware.

Do I need desk phones to use phone.systems™?

No. Calls can be made and received in the phone.systems™ app on desktop and mobile. If you prefer desk phones, each seat includes a SIP account that works with any SIP IP phone or third-party softphone.

Can I keep my existing phone numbers?

Yes. Numbers can be ported free of charge in 42 countries plus UIFN. You can also add third-party numbers or connect your current carrier through BYOC.

Can calls ring on a mobile number?

Yes. PSTN forwarding sends calls to a mobile or other external number, and each seat includes one PSTN forwarding destination. Forwarded calls may incur per-minute charges.

Is phone.systems™ a contact center?

No. phone.systems™ is a business phone system for companies whose teams handle calls as part of their work.
