Inbound Routes
An inbound route answers the question: "when someone calls this number, where should the call go?" Every phone number you receive (a DID) gets pointed at a destination.
Where a call can go
Open the Call Routing tab and map each DID to one of:
An extension
Ring one person's phone directly.
A conference
Drop the caller into a meeting room.
Time-of-day & holiday routing
Routes can change based on the clock and the calendar. Send calls to the sales queue during business hours, to an after-hours greeting in the evening, and to a holiday message on the days you're closed — all automatically.
Every destination has a sensible fallback. If a ring group or queue isn't answered, the call can roll to voicemail rather than ringing forever — you decide where.
Calls to unknown numbers
If someone dials an internal extension that doesn't exist, VoicerOnePBX answers and politely says the number isn't in service (some phones silently fast-busy on a rejection, which confuses callers — this makes it obvious).
