We have tested new mm with these modems:
* Simcom SIM7250E
* Telit GT863-PY
* Falcom Twist
* Huawei MU709S-2
all modems works ! :)
Quick question; how do all these modems implement the actual voice
channel? Is it a physical audio channel? Is it an audio channel going
through a tty? Or...?
All of these modems have an analog voice channel through a PCM hardware
codec.
