seems to me the more urgent concern in this situation might be the

<p class=MsoNormal>Known issue and not much we can do about it. Phone has
to be susceptible to RF interference by FCC rqmt. Some phone models are
more/less susceptible by housing insulation, but all do reset with enough RF
close enough.<br>

key the radio the IP phone (794x) phone reboots. Totally
