Do I need to change my business number?
Usually no. Union Bay can commonly work through forwarding or routing from the number customers already know.
The exact steps depend on the current carrier, PBX or hosted phone system. Confirm caller ID behavior, transfer support, forwarding fees and how routing changes are reversed.
Which routing patterns are common?
Common patterns are full-time answering, after-hours routing and overflow or no-answer routing.
Full-time sends calls directly to the receptionist. After-hours uses a schedule. Overflow lets staff answer first and routes only when a line is busy or unanswered.
What should be tested before launch?
Test caller ID, transfers, voicemail fallback, business-hours schedules, holidays, SMS confirmations and failure behavior.
Run realistic calls from multiple carriers and document who owns routing changes. A safe launch includes a quick way to return calls to the previous destination.
