☎️ Receive Calls

Once you’ve purchased and imported Twilio phone numbers into Sell Agent, you can start receiving inbound calls by assigning an inbound agent to the number.

​
🔗 Bind Voice Agents

To enable inbound calling, you must bind a voice agent to the number.
  • You can assign separate agents for inbound and outbound calls.
  • If you only want to make outbound calls and avoid callbacks, simply leave inboundAgentId unset.
  • Likewise, to disable outbound calls, leave outboundAgentId unset.
✅ Once you bind an agent for inbound, your number will immediately begin receiving inbound calls. Agent Assigned

​
📥 Inbound Call Webhook

In many cases, you may want to dynamically:
  • Use different agents to handle inbound calls.
  • Inject dynamic variables into the conversation (e.g., caller name, business name).
  • Pass other context-specific data.
To support this, Sell Agent allows you to configure an Inbound Call Webhook. This webhook is triggered when an inbound call is received, giving you a chance to:

​
🛠️ Option 1: Programmatically

Set the webhook when creating or updating the agent — to review all available agent parameters, check the Update Agent API. 
"webhookURL": "https://example.com/webhook"

​
⚙️ Option 2: Through Agent Settings UI

You can also configure the webhook directly in the dashboard under Agent Settings: Agent Webhook
  • Return a specific agentId
  • Provide dynamicVariables
  • Set the language, voice, or other options dynamically

​
🛠️ Example Webhook Response

Your webhook should return a JSON response like this: 
{
  "agentId": "agent_abc123",
  "dynamicVariables": {
    "first_name": "Alex",
    "company": "Mint Cafe"
  },
  "language": "en",
  "voice": "Emily"
}
