I think most of us are using 1.4 version.
Our billing software, for example, is based on some of the functionality available only in 1.4 version, it would be waste of time to port it back to 1.2 version
BTW, i tried your GSM card and it works great
I hope you will release the driver soon for 1.4 version of Asterisk
I tried the install script "install.sh" from both versions(for Asterisk 1.2.30 and 18.104.22.168) of the drivers downloaded from openvox, but both gave errors when compiling. Please see attached for the error from "opvx-bristuff-0.4.0-RC3h".
