A Wifi connection?  I guess that wifi is not like it is here.  I can get on
highspeed wifi anywhere I go in the DC Metro area for free.  Just driving
around, there is always an open access point.  When driving around, I pick
up thousands of APs in a couple miles and don't have any protection at all.

I would suspect that most road warriors have high speed data needs?  Not
sure what business you are in, but having fast internet (relatively
speaking) is a must to do work.  I am not saying to use the data supplied
from phone, if that is what you are thinking.

If your phones don't have SIP, then use callback.  You call your company, go
through whatever you seutp in the dialplan, and the phone system calls you
back as well as calling the other party.

You edited out much of the context of the conversation to support your
side.  I don't play games like that...

SIP client on the phone was an option.  Was the original question about
using DISA to save money?  Yes it was.  Now you are stating that it is
largely free.

Callback is a great solution when outbound cell phone calls quite a bit more
than your cutrate VoIP provider.  As I said, many countries do not charge
for inbound calls.

I am still clueless what your point is/was but if it is almost free then,
stick with it.  Still clueless why you posted if it almost free.

Thanks,
Steve Totaro
