while i realize that this is probably extremely wishful thinking - what are the odds that this will actually work with a nextel 7520 for the ptt feature?

i have done a bit of searching on this headset and have yet to find an answer one way or the other. it lists ptt functionality as one of it's features, but does not mention nextel or even give any further info about the feature.

i love my hbh-660, but if i could get a bluetooth headset that would allow ptt from the headset it would at least be worth a try.

TIA
