Giovanni,

I kept getting this message ... could this be causing the no-sound
from cellphone to freeswitch?

2017-09-25 00:21:48.187031 [DEBUG] mod_gsmopen.cpp:688 rev 1.9.0~64bit
[(nil)|37     ][DEBUG_GSMOPEN  688  ][gsm01     ][-1, 5, 5] read more
than 320, samples=640

No idea.

The only suggestion/hint comes to my mind is: check if during initialization, and then when calls are made or received, it uses exactly the same AT commands and arguments as in the Asterisk channel you saw is working with your modem. If not, patch it to do the same when your modem model is detected, and then post a pull request, or send me a patch.
 


Thanks,
Jeff.
