[Freeswitch-users] Unable to make calls with gsmopen

[Luiz Fernando Softov]

First, you need to check if your modem support voice calls.

Connect in the TTY (In FreeBSD i use, cu -l /dev/ttyUx.0), and send this
command

AT^CVOICE=?

Then, the return must be something like: ^CVOICE:(0)

To enable voice, send AT^CVOICE=0
To disable voice, send AT^CVOICE=1

If this wont work, and the voice is disabled, try to use dc-unlocker

Try to make a call, and send the log during the call.

You need to remove and reload this modem before, because when it enter in
this state, you was unable to do calls again.

The list before this test, must be something like this, note State = IDLE
and CallFlw = CALL_IDLE.

 CALL_IDLE

So, make a call test, and report the log, to see whats happening.
