I recently purchased a Huwaei EC360 Wireless modem from Telecom, (Under their EVDO package) and I can browse the Internet fine on Linux without any hassles. However, I also want to be able to make voice calls and send sms using this device from Linux as well.
Using minicom, I tried dialing a number by issuing the following command
ATDT1180;
The response:
NO CARRIER.
Receiving calls works fine, to answer a call I simply have to issue this command:
ATA
So now I assume there are some initialization commands that need to be passed to the device for one to make a voice call. I have searched extensively on the internet but most documentation refers to establishing data connections only.
Does anyone have any suggestions or references I can look that would help on this matter?
