I'm very unfamiliar with PTT implementations- why wouldn't the system just
use the same "registration" the phone portion of the device uses? If the
system sees that your iDen UberTalkie 3000 is connected to the network, why
does the PTT part of the device need to announce itself separately? (I'm
not doubting your statement- I'm just curious. I've just never given a
rat's hindquarters about PTT to bother to have learned how the various
systems work!)
