# Inbound Calling

> Route incoming calls from Twilio, Telnyx, or SIP to your Tig.ai agent.

Tig.ai exposes one inbound route for the workspace. Assign an inbound workflow to the phone number or SIP number that should receive calls.

## How inbound calling works

1. Your telephony provider receives the call.
2. The provider sends the event to Tig.ai's inbound route.
3. Tig.ai identifies the workspace and agent from the configured number.
4. The call is connected to the selected agent.

## Configure inbound calling

1. Open **Telephony** in the Tig.ai dashboard.
2. Add a Twilio or Telnyx configuration, or open the agent's SIP settings.
3. Add a phone number or copy the agent's SIP number.
4. Assign the agent's workflow as the inbound workflow.
5. Save and place a test call to the configured number.
