Can we read GSM payload data with OpenAT OS APIs?

Legacy Open AT

Dear All,

As I understand, in any voice call, the voice is digitized, interleaved, encrypted, … then pass to Channel encoder and to the RF stage. If I need to use my own channel encoder can read read this data via OpenAT APIs and send it to another channel encoder via UART for example?

Which API shall I use?

I know that’s crazy :smiley:

should I give up? or should I ask sierra?
The problem is that we don’t have local distributors in our country. :frowning:

Any suggestions?
