XUNA AI Conversational AI integrates with telephony infrastructure so your agent can answer calls, make outbound calls, and connect to existing phone systems. The platform supports Twilio numbers, SIP trunks, and batch outbound calling via API.

​
Twilio integration

XUNA AI configures your Twilio number automatically when you link it in the dashboard. You don’t need to set up webhooks or TwiML manually.

​

1

Open the Phone Numbers tab

In the ElevenAgents dashboard, go to Phone Numbers.
2

Add a new number

Click Add phone number and fill in the following fields:

Phone NumberYour Twilio number in E.164 format (e.g., +12025551234).
Twilio Account SIDFound in your Twilio console under Account Info.
Twilio Auth TokenFound in your Twilio console under Account Info.
3

Save the number

Click Save. XUNA AI automatically configures the Twilio number to route inbound calls to the platform.
4

Assign an agent

Select the agent you want to handle calls on this number. Click Assign agent.
5

​
Number types

XUNA AI supports two types of Twilio numbers with different capabilities:
TypeInboundOutboundNotes
Purchased Twilio numbersYesYesFull support. Numbers you own in your Twilio account.
Verified caller IDsNoYesOutbound only. Numbers you’ve verified but don’t own in Twilio.

​
Batch outbound calls

Use the batch calls API to trigger large volumes of outbound calls programmatically — for appointment reminders, surveys, or sales campaigns. 
curl -X POST https://api.xuna.ai/v1/convai/phone-numbers/batch-calls \
  -H "xi-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "agent_id": "YOUR_AGENT_ID",
    "from_phone_number_id": "YOUR_PHONE_NUMBER_ID",
    "calls": [
      {
        "to_phone_number": "+12025551234",
        "conversation_config_override": {
          "agent": {
            "first_message": "Hi Alice, this is a reminder about your 3:00 PM appointment."
          }
        }
      },
      {
        "to_phone_number": "+12025555678",
        "conversation_config_override": {
          "agent": {
            "first_message": "Hi Bob, this is a reminder about your 4:30 PM appointment."
          }
        }
      }
    ]
  }'
Pass variables to inject dynamic values into your agent’s prompt for each recipient. Configure these variables in your agent’s system prompt.

​
SIP trunking

Connect XUNA AI to your existing telephony infrastructure using SIP (Session Initiation Protocol). This lets you route calls from a PBX, contact center platform, or PSTN gateway to your XUNA AI agent.
1

Open the Phone Numbers tab

Go to Phone Numbers in the ElevenAgents dashboard.
2

Add a SIP trunk

Click Add SIP trunk and enter your SIP endpoint details.
3

Configure your PBX

Point your PBX or PSTN gateway to the XUNA AI SIP endpoint provided in the dashboard.
4

Assign an agent

Select the agent to handle calls that arrive on the SIP trunk.
5

Test the connection

Place a test call through your existing infrastructure and verify it routes to your agent.
SIP trunk availability depends on your XUNA AI plan. Contact support if you don’t see the SIP trunk option in your dashboard.
