I am interested in buying a 3G modem to
connect to some for our servers, in order to get

I am looking for a modem supported under
Linux (RH6), If someone has already made his survey on
this matter, or have proven experience on the subject,
I'd love to hear it.
A nice feature but not required, is to be
able to restart/initialize the modem remotely if it
get stuck.
Asterisk has both a Nokia (USB or Bluetooth) channel driver and
a Huawei USB channel driver.
The Huawei driver, chan_dongle, allows you to make and receive
calls and make and receive SMS messages.
You can send SMS messages from anything that can issue Asterisk
commands, which is basically any task that can execute a command
on the that computer.
If you buy a Huawei dongle look for one that allows you to
connect an outside antenna. For example, my RSSI is 8 next to my
computer, but with an external antenna 10 meter cable outside on
a railing, it peaks at 24,.
