A hosted business phone system: extensions, call routing, queues and voicemail.

Extensions and devices
Create extensions, set follow-me, and have voicemail sent to email. Yealink, Fanvil and Grandstream handsets configure themselves.
Trunks and call routing
Connect SIP trunks and send each inbound number to an extension or ring group. Route by time of day with schedules, shape outbound calls, block numbers, and lay the whole flow out on a visual canvas.
Menus that answer the phone
Digit-driven auto-attendant menus greet callers and send them to the right place.
Queues and call-centre agents
Callers wait in a queue while agents log in and out and set their status, and live statistics show how it is going.
Voicemail, conference rooms and music on hold
Mailboxes with your own greetings, messages you can play and manage in the browser, conference rooms, and music for callers on hold.
See and control live calls
A live list of calls in progress with one-click hang-up, and a searchable history of every call after the fact.
