Devices & PBX
A device is a phone's SIP account. This section covers a device's settings in depth, what happens to a call before it is answered, voicemail, and the PBX layer that sits on top of devices — ring groups, queues, IVR menus and PBX pools.
Everything here builds on step 6 of the Quick Start, which creates one device. This section goes deeper: every field on the device form, call handling per situation (busy, no answer, unreachable), voicemail, and the pieces that turn separate devices into a small phone system — ring groups that ring several phones at once, queues that hold callers in line for the next free agent, IVR menus ("press 1 for Sales"), and PBX pools that decide which devices are allowed to dial each other.

"PBX functions" is the product's name for the whole group of features on this page: ring groups, queues, IVR menus, PBX pools and a handful of built-in feature codes. If a menu or a heading says "PBX", this section is what it means.
