About OpenPhone Technologies

OpenPhone Technologies now trades as Quo, having renamed its shared business phone service. It gives a team one place for calls, texts and customer contacts so enquiries are not lost, including outside working hours.

What OpenPhone Technologies offers

  • Business numbers — new numbers set up in minutes, or existing numbers ported in from another provider.
  • Shared numbers and inbox — several staff work from one number and see the same conversation history.
  • Call routing and auto attendant — incoming calls go straight to the right person, with a call flow builder for set-up.
  • AI answering — an AI receptionist and agent pick up when the team cannot.
  • Integrations — calls and texts sync with other business tools, with an API and MCP connection for developers.
  • Number switching support — priority help during a transfer, with most customers seeing no break in service.

Who it works with

Startups and small businesses, including a law firm that uses it to text callers back straight away.
