[asterisk-users] Using a mobile phone via USB as an extension

[Nick Hill]

Hello Ishfaq

I have used Fring, but I don't believe it is capable of initiating GSM calls 
from VOIP.

As I understand it, Fring does

VOIP--->Data bearer --->Fring----->Microphone/speaker
         (wifi, 3G data)

I am proposing

3G/GSM----<>---Asterisk


the <> bit can be achieved now using Bluetooth with specific bluetooth dongles 
and specific handsets. USB especially using a USB 3G/GSM dongle would be a 
neater, and potentially more reliable solution.

If there were standard protocols which can be used over the USB GSM modem 
interface which can be used to set the device to receive voice calls and send 
them over the USB interface, and to establish a voice call via the USB 
interface, this could potentially be a neat solution.

However, I guess that even if a lot of equipment nominally supports such an 
interface, it may not be well tested. Interesting for a hack.
