I have a number of users in a shared/secure office with wired headsets, and their phones (5320e) setup so that they are always in headset mode (headset port instead of handset port, hookswitch disabled).
Apparently, if they put their hand over the mic, or do a number of other things, the phone gets confused and thinks that their wired headset has malfunctioned. When that happens, the phone automatically switches from headset mode to speakerphone, which is highly disruptive.
Not only is it an inappropriate room for speakerphone to ever be used, but because they are in headset mode 100% of the time they don't have a Headset button programmed on their phone. So, when this happens, they have to either drop their call and dial the feature access code for headset mode to fix it, or finish their call on speakerphone.
Any thoughts on how to stop this from happening?
