1. Create Inbound SIP Trunk

To begin connecting your DIDWW account with the ElevenLabs Agents Platform, first create an Inbound SIP Trunk. This trunk will establish the path for incoming calls from your DIDWW numbers to reach ElevenLabs.

Before You Begin

• An active DIDWW account is required. Sign in to DIDWW or Create DIDWW account .

• At least one active DID number with capacity to receive incoming calls is required. Buy Numbers .

• Access to Encryption is required to use secure SIP signaling (TLS) and media (SRTP). To enable encryption, contact sales@didww.com .

Step 1: Create New SIP Trunk

1. In the DIDWW User Panel , go to Voice > Inbound Trunks.

2. Click Create New > SIP Trunk.

Fig. 1. Creating a new inbound SIP trunk

Step 2: Configure General SIP Trunk Settings

In the Create Inbound SIP Trunk form, enter the main requirements to route the calls to ElevenLabs platform.

1. Enter a descriptive Friendly Name for the trunk (e.g., ElevenLabs).

2. Copy and paste the ElevenLabs SIP endpoint Host: sip.rtc.elevenlabs.io

3. Select Transport Protocol Type and Port for SIP signaling: TCP (Port 5060) or TLS (Port 5061).

Warning

2. Create Outbound SIP Trunk

To configure outbound calling from your ElevenLabs Agents Platform, create an Outbound SIP Trunk in the DIDWW User Panel. This setup enables ElevenLabs Agents to place outbound calls through DIDWW to external phone numbers when required.

Before You Begin

• Access to DIDWW Outbound Trunks is required for making outbound calls. See Get Access to DIDWW Outbound Termination.

• Access to Encryption is required to use secure SIP signaling (TLS) and media (SRTP). To enable encryption, contact sales@didww.com .

Step 1: Create New Outbound Voice Trunk

1. In the DIDWW User Panel , go to Voice > Outbound Trunks.

2. Click Create New.

Fig. 8. Creating a new outbound SIP trunk

Step 2: Configure Authentication

1. Update the Friendly Name (e.g., ElevenLabs).

2. Keep the default Credentials & IP-based authentication method selected. The SIP digest credentials (username and password) will be provided after the trunk is created.

3. In Allowed SIP IP addresses, enter the public IP address or subnet from which ElevenLabs will send outbound SIP traffic.

Note

ElevenLabs SIP traffic originates from IP ranges that may vary depending on your plan or region.
Refer to the official ElevenLabs documentation for the most up-to-date information: ElevenLabs SIP Trunking IP Information

Warning

You can allow all traffic by adding 0.0.0.0/0, which removes all IP restrictions.
Although SIP Digest Authentication will still verify requests using valid credentials, this setup is not recommended.
Restrict access to known ElevenLabs IPs whenever possible.

Fig. 9. Entering allowed SIP IP addresses for outbound authentication

Step 3: Configure Media Encryption (Optional)

Note

To enable encryption on your account, please contact our sales department at sales@didww.com .

Media encryption (SRTP) is optional. This feature improves security by encrypting RTP traffic.

1. Expand the Media configuration section in the configuration form.

2. In the Media encryption mode field, choose the preferred SRTP method from the list:

   • SRTP SDES – Uses Session Description Protocol Security Descriptions.

   • SRTP DTLS – Uses Datagram Transport Layer Security for key negotiation.

   • ZRTP – Uses ZRTP key agreement protocol.

Fig. 16. Configuring outbound SIP settings

Step 5: Import Your Phone Number

When the main phone number configuration is complete, click Import to add your DIDWW number to ElevenLabs.

Note

To receive inbound calls, you only need to enter your DIDWW phone number.

Fig. 17. Successfully imported phone number and activated SIP trunk

Step 6: Assign Voice Agent

To complete the setup, assign an existing ElevenLabs Voice Agent to your imported DIDWW phone number. When someone calls your DID number, this agent will answer and manage the conversation.

1. Open the Edit page for your imported phone number in the Phone Numbers section (click the number to open it).

2. In the Agent field, select the Voice Agent you want to handle inbound calls from the dropdown list.

Note

For more information on creating or managing agents, see the ElevenLabs Quickstart Guide .

Fig. 18. Assigning a Voice Agent to handle calls from the DIDWW number

Step 7: Make a Test Call to Your DIDWW Number

Place a test call to your DIDWW phone number to confirm that inbound calls are correctly forwarded to the ElevenLabs SIP URI. The assigned Voice Agent should answer and handle the call.

Verify that SIP signaling, authentication, and media encryption (if enabled) are functioning as expected.

Note

You can review call activity and verify call status or error codes in the DIDWW Inbound Call Logs. See Inbound Call Logs for more details.
