Your native format is the format that the phone actually uses (on the wire). The read and write formats are what Asterisk expects to send to and receive from the application, because Asterisk has set up a translation path to ensure that the application gets a format that is more conducive to its purpose. Internally to Asterisk, when you ast_read() a frame from the channel, you should expect that, when the frame is a voice frame, the frame will be in the ReadFormat. And, when you ast_write() a voice frame to that channel, it should be in the WriteFormat. -- Tilghman -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
