<div dir="ltr"><div>Sorry for being a little ambiguous. I am looking at this function:<br><br></div><div>static int console_write(struct ast_channel *chan, struct ast_frame *f)</div><div>{</div><div><span class="" style="white-space:pre"> </span>struct console_pvt *pvt = ast_channel_tech_pvt(chan);</div>
<div><br></div><div><span class="" style="white-space:pre"> </span>Pa_WriteStream(pvt->stream, f->data.ptr, f->samples);</div><div><br></div><div><span class="" style="white-space:pre"> </span>return 0;</div><div>
}<br><br>However, I dont use PortAudio, instead I have my own stream that instead will send throught a socket the raw buffer of the frame. I just need to be able to get the raw voice buffer off of the phone every 10ms doing 8khz raw PCM data (SLINEAR). That is all I am trying to get from the console_write. Is there a better way to get that voice data coming from the endpoint device?<br>
<br>Basically, I have a SIP configured phone and my custom driver, so when console_write gets hit, I should be taking the SIP phone's voice frames and then I want to send those on their way with my stream to a totally separate device. <br>
