Overflow call answering: when all your lines are busy
Overflow call answering catches the calls that slip past a busy team: your number diverts on busy or no-answer, and every overflow caller is answered instead of queued or lost.
Where the calls leak
- Both lines engaged during the morning rush
- The one person who answers phones is at lunch, on leave, or already on a call
- A campaign lands and twenty people ring in the same hour
Why AI is the perfect overflow
Overflow traffic is bursty — precisely when human bureaus queue. Odette answers simultaneous calls on the first ring (capacity is set by your own Twilio and ElevenLabs plans, so check it against your busiest hour), answers questions from your website, takes messages, and can pass genuinely urgent callers back to your team. You keep answering the calls you can; Odette catches the rest, 24/7.
Switching over is one divert code on your existing number — no number change, no porting, no downtime. See pricing and what missed calls really cost.

What is overflow call answering?
A safety net for calls you cannot take: your number diverts to the answering service only when your line is busy or unanswered after a set number of rings. Quiet days, nothing changes; busy days, every extra caller still gets answered.
How do I set up overflow answering?
Ask your phone provider to set divert-on-busy and divert-on-no-answer to your answering service's number (a few minutes on most systems, including mobiles). With Odette, calls that divert are answered by AI instantly — even five at once.
Does overflow answering work during marketing campaigns?
It is made for them. When an ad or mailout spikes your call volume, humans queue callers; an AI receptionist answers every simultaneous call, captures every lead, and transfers or messages per your rules.
