[Asterisk-Users] WI FI IP phones??

[Dean Collins]

Nope I works differently, they use it in a few hospitals here in Sydney,
basically it works like the new gsm 'push to talk' service being rolled
out, basically limited number of frequencies, voice 'envelope' being
delivered as a best case availability basis.

It's not a 'held up' tdma style call flow that wifi phones are.

Cheers,
Dean

I guess vocera doesn't have any RF engineers to tell them they can't do
it.
