Hi there, I wanted to make a voip application for embedded devices, and wanted to use Pjsip libraries. This application won't use any gui, but simple i/o lines to start or stop call. Embedded boards often don't have audio devices, or maybe have only audio output, so I made a simple audio sampler with a microcontroller that outputs the stream to a serial line (such as rs-232). In linux it is easy to listen to the stream with "play /dev/ttyS0" (plus some format parameter). But if I want to use that stream with another application such as pjsip, that's not so easy :( So I want to ask you a piece of advice. Is it simpler to add a module to pjsip, or to make a kernel module to add a virtual sound card ?
