How to Connect Your Phone Number via SIP Trunking (Step-by-Step)

Awaz.ai supports SIP trunking to let you use any VoIP provider’s phone number for making and receiving calls directly through our platform.

Updated over a month ago

Why Integrate via SIP Trunking?

Awaz.ai’s SIP Trunking integration allows you to connect your existing VoIP provider’s phone number directly to our platform. This guide will help you:

✔ Use your own VoIP provider’s number for inbound and outbound calls
✔ Configure your SIP credentials (username, password, host, port) in Awaz.ai
✔ Test and verify that calls route through Awaz.ai using your SIP trunk
✔ Troubleshoot common SIP connection issues


Step 1: Gather Your SIP Credentials

  1. From your VoIP provider, obtain:

    • Username (SIP User): the account or extension name.

    • Password: the SIP account password (ensure it contains no special characters, since Twilio blocks those).

    • Host (Domain): the SIP server domain or IP address.

    • Port: default SIP trunk port is usually 5060 by default (confirm with your provider if needed).

    • Phone Number: the DID you want to register.

  2. If you haven’t already, confirm with your provider that:

    • Outbound traffic to Awaz.ai’s SIP IP ranges is allowed.

    • Your chosen password uses only alphanumeric characters (no special symbols like @, !, or #).


Step 2: Enter SIP Details into Awaz

  1. Visit https://app.awaz.ai and sign in with your admin credentials.

  2. In the left sidebar, click Settings.

  3. In Settings > Integrations.

  4. In Phone > Click Buy Phone (even though you’re not purchasing; this is where you manage external numbers).

  5. Choose the SIP and enter SIP Trunk Details

    • Phone Number: Enter your existing DID

    • Host (Domain): Enter your provider’s SIP server domain (e.g., sip.brazilprovider.com).

    • Port: Typically 5060. If your provider uses a different port, enter that instead.

    • Username: Paste the SIP User you retrieved from your provider.

    • Password: Paste the SIP password (must be alphanumeric only).

  6. Click Save to register this SIP trunk.

💡 Tip: If you receive an error, double-check that there are no special characters—Twilio (which handles our SIP redirection) blocks them.


Step 3: Verify Connection and Trigger Calls

  1. To test outbound calls:

    • Create a test campaign or agent with that SIP trunk as the outbound channel.

    • Place a call to any valid number—Awaz.ai should route through your VoIP provider seamlessly.

    • You may also use the test call function within the Agent's settings.

  2. To test inbound calls:

    • From an external phone, call your SIP-provided DID.

    • Awaz.ai’s call flow will answer according to your agent configuration.

💡 Tip: If inbound calls fail to ring in Awaz.ai, log in to your SIP provider’s portal and confirm that they’re not blocking Awaz.ai’s calls.


Troubleshooting Common Issues

Issue: Connection Fails Immediately After Saving

  • Cause: Incorrect credentials (username/password) or host.

  • Solution:

    1. Re-copy your SIP User and Password—ensure no trailing spaces.

    2. Confirm the Host domain exactly matches your SIP provider’s server.

    3. Verify the port (default 5060) is correct.

Issue: Authentication Errors

  • Cause: Password contains special characters or SIP provider blocking Twilio’s IP.

  • Solution:

    1. Change your SIP password to use only letters (A–Z, a–z) and numbers (0–9).
