<div dir="ltr">Hi guys,<div>I think i know the problem you are facing. There has been a period where at least part of the manufactured 9971 had a major Issue with the quality of the Display/Touchscreen assembly which resulted in those ghost calls. The newer firmwares of those phones introduced optimizations for the touch screens to counter the problem but some phones might still experience the issue.</div>
<div>In this case i think the only option is to RMA the phone or if it is a large scale (many phones) issue to contact your cisco reps.</div><div><br></div><div>cheers</div><div>bernhard</div><div><br></div></div><div class="gmail_extra">
