The no-code path. Connect your number in the Unpod Studio to get an Unpod SIP trunk (one endpoint, inbound + outbound), then import that number into ElevenLabs Conversational AI over SIP and attach an agent. Prefer code? See the API guide.
You need: an Unpod number on a Bridge, and an ElevenLabs account with a Conversational AI agent (the agent needs a First Message and a selected voice).
We only show the Unpod-side screens here. Treat your SIP trunk username/password as secrets - never paste them into shared docs or screenshots.

​
Part 1 - Connect the number in Unpod

1

Connect your number

In Telephony, select your number (shown as Not Linked) and click Connect to set up its SIP trunk.Unpod - number Not Linked, Connect
2

Point the trunk at ElevenLabs (inbound)

In the trunk panel, set the Trunk Origin Endpoint Details to ElevenLabs’ SIP host:
  • SIP URI / address - sip:sip.rtc.elevenlabs.io:5060;transport=tcp (or port 5061 with transport=tls for TLS).
  • Port 5060 (TCP) / 5061 (TLS).
  • Allowed IPs / CIDR - optional source allow-list.
Click Save. The number then shows Linked · Unpod SIP Trunk.
Calls Unpod sends to ElevenLabs use the form sip:<your-number>@sip.rtc.elevenlabs.io:5060 (identifier + domain).
3

Copy the origin-endpoint credentials

Under Origin Endpoint Details copy these - you’ll paste them into ElevenLabs next:
  • Address - e.g. sip-lb1.unpod.tel
  • Port / Protocol - 5060 / TCP
  • Username and Password (under Authentication)
Unpod - linked trunk origin endpoint credentials

​
Part 2 - Import the number into ElevenLabs

In the ElevenLabs Agents dashboard, open the Phone Numbers section.
1

Open Phone Numbers → Import

Click Import number, then choose Import a phone number from SIP trunk.ElevenLabs - Phone Numbers, Import number
2

Basic configuration

In the Import SIP Trunk panel set:
  • Label - a descriptive name.
  • Phone Number - your Unpod number in E.164 (e.g. +918071539111), or a SIP extension / identifier.
ElevenLabs - Import SIP Trunk panel
3

Inbound configuration

Under Inbound Configuration (forwards calls to the ElevenLabs SIP server):
  • Media Encryption - Allowed (use Required with TLS for production).
  • Allowed Numbers (optional) - leave empty to allow all.
  • Allowed Source IP Addresses (optional) - 0.0.0.0/0 to allow all (TCP/TLS only; restrict in production).
4

Outbound trunk - point back at Unpod

So ElevenLabs can send calls to Unpod, enter the Unpod origin-endpoint values from Part 1:
  • Address - your Unpod address, hostname only, no sip: prefix (e.g. sip-lb1.unpod.tel).
  • Transport Type - TCP (or TLS).
  • Media Encryption - Allowed (use Required with TLS for production).
  • SIP Trunk Username / SIP Trunk Password - the Unpod Username / Password.
Click Import.
Production: ElevenLabs recommends TLS transport + Required media encryption (TLS 1.2+). Your system must support G711 or G722 codecs (8 kHz / 16 kHz) or resample.

​
Part 3 - Attach your agent

1

Attach the inbound agent

Open the imported number and attach your Conversational AI agent from the dropdown. Incoming calls now route through ElevenLabs to that agent.
2

(Optional) Make an outbound call

From Phone Numbers, select the imported number → Make Outbound Call → choose the agent → enter the destination in E.164. Check the agent’s Call History / Conversations for transcripts and recordings.
