About phone.systems™
Every call, handled your way. phone.systems™ is a business phone system by DIDWW, built around the way your company works.
A business phone system by DIDWW
phone.systems™ is a cloud business phone system — a cloud PBX with its own calling app — built by DIDWW. Numbers, users, call flows, calling apps, call recording, call history and AI call insights are managed in one account.
DIDWW is a telecom carrier. It provides phone numbers in 93 countries, holds telecom licences in 30 countries and ports numbers free of charge in 42 countries plus UIFN. Because the carrier and the phone system come from the same operator, customers get numbers, voice connectivity and the phone system from one provider — and can still bring their own carrier.
What we focus on
- Routing that follows your business Opening hours, teams, departments and locations decide where calls go, and the rules are changed in a visual editor.
- Calling from any device Team members use company numbers in the app on desktop and mobile, or on SIP phones.
- Understanding calls Call history, statistics, recordings and AI call insights show what happened on each call.
- Choice of connectivity Use DIDWW numbers, your own carrier, or both.
phone.systems™ is a business phone system, not a contact center. It is designed for companies whose teams handle calls as part of their work.
