One-Way or No Audio During Calls

No audio during a call? Changing Firewall routing might solve it.

If you are noticing that calls connect, but there is no audio flowing in one or both directions, the most common cause of that is that the audio data is being routed incorrectly after the call is established. Try the following steps for solving the audio routing.

Step 1. Change Firewall / Network Traversal Strategy

Try changing the Firewall / Network Traversal settings to work around the network routing issues. 

Bria Solo/Teams 

Firewall settings can be configured from the Bria Admin Portal. These settings are not available within the app. 

  1. Log in to the admin portal, go to the Voice & Video tab, and edit your server configuration.
  2. In the Service Settings tab, try changing your Firewall Method to one of the available options.
    • If you set it to STUN, you can use stun.counterpath.com as the firewall server URL (it does not require a username or password).
  3. Remember that once you make a change in the admin portal, you need to log out and back in on the Bria app to download the updated settings. 

Bria Enterprise / Bria Mobile

Network Traversal settings are available within the Bria app.

  1. Within the Bria  app, go to Settings > Accounts, and select the SIP account you are having an audio issue with.
  2. Under Account Details, go to Account Advanced  > Network Traversal Strategy.
  3. Try changing the Strategy to one of the available options. 
    • If you need a STUN server, enter stun.counterpath.com (it does not require a username or password).
  4. Apply changes.

     

    Step 2. Disable SIP ALG

    If Step 1 does not work, another troubleshooting step is to disable SIP ALG on your local router settings, which sometimes can cause one way audio. Refer to your router's documentation for how to disable it.
