USG Flex 100 error phonebar Java

Nicola_Santalucia

Hello everyone. I have a problem with my zyxel USG flex 100. It happens that while using a phonebar Java connected to a VPBX often error: Unable to communicate with server. I don’t understand what it depends, if I remove from the network the firewall is using a normal router the problem disappears.
