Note: Video walkthrough for Grandstream GXP/Telnyx configuration coming soon. Check back as we update our docs.

1. Get your device's IP address and log into your phone's web portal

In this step, you'll obtain the IP address from your GXP, which you'll need to log into the web portal in the next step.

  1. From your phone, navigate to Menu >> Status >­> Network Status >> IPv4 Address and take note of the IP address on this screen. You'll need it next.

  2. On a computer connected to the same network as your phone, open a web browser and type http:// followed by the phone's IP address into the address bar of your browser.

  3. Log into the portal. Out of the box, the default credentials are:

    1. Username: admin

    2. Password: admin

2. Configure your Grandstream GXP

In this step, you'll create a SIP trunk and connect your phone to Telnyx.

  1. Click on Accounts in the top menu.

  2. Expand the account you're looking to configure and click General Settings.

    You can also use the top navigation to get here if you want.

  3. On this page, enter the following information:

    1. Account Name: Give it a name that makes sense for you

      SIP Server: sip.telnyx.com

      SIP User ID: Your Telnyx SIP account username

      Authenticate Password: Your Telnyx SIP account password

      Name: This is your caller ID. You can choose whatever you like, but keep in mind the following naming conventions:

      1. Caller ID Name should be in capital letters. This will appears more clearly/visible on some devices.

      2. You must NOT use any special characters, as they will not be displayed. Spaces are allowed.

      3. Some of regular Canadian providers will not show more than 15 characters. We suggest shrinking or adapt your caller ID.

    2. Voice Mail Access Number: *97

  4. Now, while still in Accounts > Account 1 (or the account you want to configure) click on SIP Settings > Basic Settings and provide the following information:

    1. SIP Registration: Yes

    2. Register Expiration: 5 (this is in minutes)

    3. Enable OPTIONS Keep Alive: Yes

    4. Local SIP Port: 5060 if you have not enabled TLS encryption. If you have, choose 5061.

    5. SIP Transport: UDP or TCP if you have not enabled TLS encryption. If you have, choose TLS/TCP.

    *This screenshot demonstrates a connection that uses UDP transport.

  5. Click Save and Apply.

That's it! You've finished configuring your Grandstream GXP profile, and can now start testing calls!
