Why it matters for your business

This is the phone power big brands pay for, built into the same inbox as your texts: extensions, IVR 'press-1' menus, ring groups, business-hours routing, voicemail and transfer. Whoever answers already sees the caller's full conversation history, so calls stop being cold. And every call can be recorded, transcribed and summarized — turning voice into data on the contact.

Questions & answers

Is the phone system really included, not an add-on?

The PBX — extensions, IVR, ring groups, routing, voicemail and transfer — is part of the platform. Extra lines, toll-free and vanity numbers and call recording are the priced add-ons.
