Asterisk has both a Nokia (USB or Bluetooth) channel driver and a
Huawei USB channel driver. <br>
<br>
The Huawei driver, chan_dongle, allows you to make and receive
calls and make and receive SMS messages. <br>
<br>
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. <br>
<br>
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,.<br>
