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.
