Hi all,
We noticed that our GS 500 cannot register with office 365. The Device is on Firmware version 6.2.1-540239 . Looks like Microsoft keeps rejecting connections from the device. See logs and screenshots for more details. All required network ports have been opened and configurations look alright. Any idea? I am getting crazy to find a solution. Log of a GS500 attached and screenshot of SIP Registration error also attached
Many many thanks
