any reason why you are not using oFono. It is a full telephony stack and
does a lot more things in the background that are mandatory. And you
would not have to implement the whole USSD support all by yourself.

Especially when we merge the integrated PPP support into oFono, then it
might be a nice alternative for you actually.
