Does anyone know if it's possible, or -- better -- have experience
using a cell phone as a dial up modem?
I'm wondering about doing something as an alternative to a traditional
POTS modem connected to a VoIP ATA. I'd think that treating the phone
as a traditional modem with venerable Hayes AT commands might be more
reliable than trying to do dial up connections across VoIP.
It's been *YEARS* since I've tried to connect a modem to a serial port
on a PC, universal or otherwise.
Does anyone have any experience with or thoughts about doing this?
I have used such as US Robotics with a vonage voip account pad. Sends
and receives faxes quite well, as well.
The cell phone perhaps could provide a connection. A friend used the
cell via Wifi tethering to a PC. Then set up a route command to make it
primary and function as a router outside. Then connect to the network
via other devices, including the voip box.
We used this for a company I did IT chores for in a pinch when bell
couldn't make up its mind for our DSL, and pissed off T-Mobile. But a
couple of devices behind the tether didn't piss it off. Using 10 pcs
did though. (FWIW).
The vonage for voice worked, but not sure if it could do much more than
2400 or such (whereever you can function in modem protocol land w/o
phase coherency.)
We were in the center of Santa Ana with a very close in cell site, BTW.
Thanks
Jim
