How it works
There are several standard ways to route calls to an AI answering service. None of them require replacing your current number or involving IT.
Your business keeps its current phone number. You configure your carrier or phone system to forward calls to a second number — the one assigned to your AI assistant — under specific conditions.
Most carriers support this out of the box. Common forwarding types:
Carriers like AT&T, Verizon, T-Mobile, Google Voice, and RingCentral all support conditional forwarding, usually via a short code (e.g. *71, *92) or a web portal. No IT involvement required for basic setups.
From the caller's perspective, the call is seamless — they dial your number as usual.
A DID (Direct Inward Dialing) is a real, dialable phone number provisioned from a carrier and assigned to a platform or endpoint. It looks and behaves like any other phone number.
When you use a DID as your main business number, all inbound calls arrive at the AI assistant first. The assistant then decides what to do: answer the call, collect information, or forward to a staff member based on the time of day, the caller's need, or a schedule you configure.
This gives you full control of the routing layer before any call reaches a human.
If your business uses a PBX or VoIP phone system (Cisco, Avaya, Asterisk, FreePBX, 3CX, and others), you can route calls to an AI assistant directly — no special integration required.
From the PBX's perspective, the AI assistant is just another PSTN destination or SIP endpoint.
| I want to keep my current number and only use AI after hours | Option 1 — set up conditional forwarding (no-answer or scheduled) on your existing line. |
| I want the AI to answer all calls and route to staff during business hours | Option 2 — use a dedicated number as your main line and configure a routing schedule. |
| My business already has a PBX or multi-line phone system | Option 3 — configure your PBX to forward overflow or after-hours calls to your AI assistant number. |
| I just want to try it without changing anything | Option 1 — forward your line to the AI number during a test window. Revert anytime. |
