Ok, after a lot of work to configure this to work as remote extension to Freepbx server, we got the phone working normally when using the handset, however and super strange when we click on either one of the direct lines or the speaker phone button, the phone automatically resets. It gets the microphone button red and both speaker and headset buttons green and jumps right into the Initialing Network and then goes back to normal displaying all four registered lines. Funny thing is not a full reboot as this takes longer, but nevertheless there's something odd here, power supply is standard 5V 2A, so not sure what else could it be. Does anyone had similar issues with their phones?
Thanks.,
Mark
