Hi there,

I have NEC SV9100 IP extension with Plantronics CS540 headset on EHS cable. I Have an issue when the answer key is pressed there is a long delay on answer then the headset goes off hook again second time.

I have tried the headset and EHS cable on other extension with no issues. I signed the IP extension out and signed in a newly created IP extension in on new number with no issues using the same headset and EHS cable.. I suspect the user activated a feature by mistake. We do not want to change the extension number.

Is the a way that I can see what feature is active causing these headset issues so that I can clear or disable the feature?

Please not the headset worked fine before. I have confirmed the headset key on key 25. Would be grateful for any advise.

kind regards
