LB2120 Feature request - ping test fail over setting

Hello,

The LB2120 is a great device.  It is able to do almost everything I want.  However I wish I had a setting where I could configure how often the ping test for detecting failing over happens.  Meaning the time interval for when the ping test happens and either fails or successeds to determine if the device should fail over from the landline connection to the celluar connection.

 

Is this feature available and I'm not aware of where it is?

 

If its not available can the be added to a firemware update.

 

Thank you,

Ryan

    Please, please, please....

     

    I find the LB2120 pulls in too soon.

     

    The issue is that Zoom or Skype will handle certain amounts of interruption when the ADSL ping rate drops out and is re-established say 10 to 15 seconds later and automatically re-connect.

     

    The LB2120 fallover timing means that apps such as Zoom and Skype see a new route when the fallover kicks in. That's fine, however the fallover interval needs to be adjustable to avoid it activating too soon. As otherwise I frequently have to re-connect to Zoom or Skype meetings etc. Which has people seeing me "exit" and "re-join" meetings. Whilst technically accurate, its annoying to everyone; especially if its access on approval basis meetings!

     

    What is really needed is sensitivity and hysteresis. i.e. ability to set how long to wait before fallover and minimum period before switching back again (actually test the wireline), an option for manual switch back and perhaps switch back (test the wireline again) at a set time or period.

     

    At the moment I have a work around based on a Raspberry Pi and some Python scripts that lets me set my own fallover behaviour. It's not elegant but it flies. Would prefer to manage it through the LB2120 though as should be the case. I feel it's a key feature that should be available for configuration.
