Everything a business phone system needs

Not a hosted seat — every one of these ships in the source code, running on your own infrastructure, under your own brand.
Extensions & ring groupsEvery desk gets its own extension; calls can ring one person, a group, or hunt through a list until someone answers.
IVR menus & call routingBuild the menu callers hear and where each option sends them — reception, a department, or straight to voicemail.
Call recordingRecord inbound and outbound calls for training, dispute resolution or compliance, retrievable against the call record.
Number portingA built-in workflow to port numbers in, or provision new local numbers through your own carrier connections.
Live CDRs & billingEvery call — who, when, how long, what it cost — feeding straight into your own multi-tenant billing engine.
Softphone & mobile appsAnswer and make calls from a desk phone, a softphone or a mobile app, all on the same extension.
