ElevenLabs (API)

The programmatic path for the Unpod side: create a SIP trunk pointed at ElevenLabs and attach your number. The trunk’s origin endpoint is what you then register in ElevenLabs as a BYO SIP trunk - see the Dashboard guide for the ElevenLabs-side screens.

Base URL: https://unpod.ai/api/v2/platform/ Every request needs Authorization: Token <your-api-key> and an Org-Handle header. See Authentication.

Prerequisites

An Unpod API Token and Org-Handle.
A number in your org (we’ll fetch its id below).

1. Find your number

cURL

curl https://unpod.ai/api/v2/platform/telephony/numbers/ \
  -H "Authorization: Token $UNPOD_TOKEN" \
  -H "Org-Handle: $ORG_HANDLE"

Response (200)

{
  "status_code": 200,
  "message": "Telephony numbers fetched successfully.",
  "data": [
    { "id": 501, "number": "+15551234567", "state": "NOT_ASSIGNED", "active": true }
  ]
}

List Numbers reference

Full request/response schema.

2. Create the SIP trunk to ElevenLabs

Point the trunk’s sip_url at ElevenLabs’ SIP host. One trunk carries both inbound and outbound.

cURL

curl -X POST https://unpod.ai/api/v2/platform/telephony/trunks/ \
  -H "Authorization: Token $UNPOD_TOKEN" \
  -H "Org-Handle: $ORG_HANDLE" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "ElevenLabs trunk",
    "sip_url": "sip:sip.rtc.elevenlabs.io:5060;transport=tcp",
    "transport": "tcp",
    "port": "5060"
  }'

Response (201)

{
  "status_code": 201,
  "message": "Trunk created successfully.",
  "data": { "id": 21, "name": "ElevenLabs trunk", "sip_url": "sip:sip.rtc.elevenlabs.io:5060;transport=tcp", "transport": "tcp", "port": "5060", "active": true }
}

Create Trunk reference

All request fields (sip_url, auth_username, auth_password, transport, port, source_ips).

3. Attach your number to the trunk

Map the number from step 1 (its id) to the trunk from step 2 (its id). The response returns the origin endpoint - the address + creds you register in ElevenLabs.

cURL

curl -X POST https://unpod.ai/api/v2/platform/telephony/trunks/21/attach-numbers/ \
  -H "Authorization: Token $UNPOD_TOKEN" \
  -H "Org-Handle: $ORG_HANDLE" \
  -H "Content-Type: application/json" \
  -d '{ "number_ids": [501] }'

Response (201)

{
  "status_code": 201,
  "message": "Numbers mapped to trunk.",
  "data": {
    "trunk_id": 21,
    "origin_endpoint": {
      "ingress": "sip:sip-lb1.unpod.tel",
      "dids": ["+15551234567"],
      "accepted_source_ips": [],
      "region": "ap-south"
    }
  }
}

The origin_endpoint.ingress (plus the trunk’s auth_username / auth_password) is what you enter in ElevenLabs’ BYO SIP trunk.

Attach Numbers reference

Path params, request body, and the full origin-endpoint response.

Configure the ElevenLabs side

The Unpod side is done. Import the number into ElevenLabs over SIP. This is ElevenLabs’ own API (api.elevenlabs.io, xi-api-key header). Use the origin endpoint from step 3.

4. Import the number from SIP trunk

cURL

curl -X POST https://api.elevenlabs.io/v1/convai/phone-numbers \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "sip_trunk",
    "phone_number": "+15551234567",
    "label": "Unpod trunk",
    "outbound_trunk_config": {
      "address": "sip-lb1.unpod.tel",
      "transport": "tcp",
      "media_encryption": "allowed",
      "credentials": {
        "username": "<unpod trunk username>",
        "password": "<unpod trunk password>"
      }
    },
    "inbound_trunk_config": {
      "allowed_addresses": ["0.0.0.0/0"]
    }
  }'

outbound_trunk_config.address = your origin_endpoint.ingress host (no sip:). The response returns a phone_number_id - attach your Conversational AI agent to it.

Full phone-number import + agent assignment (this is ElevenLabs’ API).

Troubleshooting

Status	Meaning	Fix
`400` on `/trunks/`	Missing `sip_url`	Send `sip:sip.rtc.elevenlabs.io:5060;transport=tcp`
`400` on attach	Number not in org	Use a valid `id` from GET /numbers/
`401`	Bad Unpod token	Verify `Authorization: Token …`
`403`	Wrong org	Verify the `Org-Handle` header
