    NEC DT900 VoIP Phone: Log Off Prompts Exit & Resets

    DoubleDizzle, After discussing it with our CrowdStrike team, nobody believes that it's installed on the phones. It's been suggested that I implement WireShark on one of the switches that has a phone connected and go from there. Any thoughts on that or anything that might point us back to...

    NEC DT900 VoIP Phone: Log Off Prompts Exit & Resets

    DoubleDizzle, That is exactly what is happening to the newly provisioned DT900s that are on Firmware (03.00.02.00). Any ideas on how to investigate and possibly resolve this here? We're utilizing CrowdStrike. Thank you.

    NEC DT900 VoIP Phone: Log Off Prompts Exit & Resets

    Is this what you're inquiring about? No, we're not using NAT or VPN. Also, while in WebPro, it doesn't present an option for DT 900, only DT 700/800. I've previously had the thought that the DT 900 isn't supported well, but the fact that we've had some DT 900s that were deployed over a year...

    Currently 15-05-39 - CTI Override Mode: Disable Does this need to be switched to Enable to prevent this? Licensing seems adequate:

    To my knowledge, all of the extensions work and are unique by being assigned a four digit extension. How would I look at the licensing to ensure we were covered? Also, I'm not familiar with hot desking. As far as I know this issue doesn't happen to our existing DT800 phones or newly...

    NEC DT900 VoIP Phone: Log Off Prompts Exit & Resets

    We're running NEC SV9100 (WebPro 10.00.00) and have stable NEC DT900 phones on Firmware Version (02.04.00.00) that have been online for over a year without interruption. Recently, we've provisioned more DT900 phones on Firmware Version (03.00.02.00), but occasionally they present a screen with...
