Overflow Handling
Routing calls to a live answering team only when the client's own phones are too busy to answer.
What it is
Overflow handling is conditional forwarding. The client's own receptionist or in-house team takes calls during normal volume, but when lines are full or the call rings unanswered for a configured number of seconds, it spills over to the answering service.
How it works
The client's PBX is configured with a 'no-answer' or 'busy' forward to a dedicated DID at the answering service. Operators see the call as belonging to that client's account and follow its standard script, indistinguishable from in-house staff to the caller.
Overflow rules can be tuned by ring count, time of day, or call queue depth.
Why it matters
Overflow lets a business right-size its in-house phone team without sacrificing customer experience during spikes — Monday mornings, a sudden weather event, or a marketing campaign that lands.
