Hi, I want to implement PJSIP on an embedded ARM9-based processor module supplied with 2.6.34 Linux to create an embedded SIP phone. The Linux kernel provided isn't setup for any sound devices and doesn't have sound device drivers but there are C methods to write to the A/D and DAC devices directly. Is it possible to bypass PJSIP's operating system sound device driver access and instead access sound devices directly or can someone suggest a better way? If it is possible how would I do it and what methods would I need to implement? (In a future development I plan to port PJSIP on another embedded platform not running Linux but instead running MQX or Keil RTX so again I need to implement access to sound devices somehow.)
