    This looks like a nice module for industrial controllers and GSM VoIP gateways.

    I have 2 questions, the answer to which I’ve not found in the data sheet or app notes.

    1. If it possible, and if so how does one use the PCM bus for audio (as opposed to the analog interface). What is the timing for this interface?

    2. How does one use the raw data interface? I see that the module provides a TCP/UDP socket interface, but I need to use the native TCP/IP stack in the Linux kernel running on our micro controller. Is there a SLIP or PPP interface, or something like that?

    Thanks in advance to anyone who knows or has tried either of these, J.

No public wish lists :(
