TG and TA Upgrade Important Note

Some users reports that, their gateways became unresponsive after firmware upgrade. This only happens for TG and TA gateways.
In fact, we already announced the important note on the firmware downlaod page:

The firmware for TGv3 and TAv3 are not allowed for the previous products.


You would see the difference between different versions to distinguish them.

  • TGv2: 5X.X.X.X
  • TGv3: 91.X.X.X


  • TA FXS v1/V2: 40.X.X.X, 41.X.X.X
  • TA FXS v3: 47.X.X.X
