What I found is you really need to lock things down to 8000 clock speed right through the pipeline, not just the audio driver, use simple echo (the regular and speex algorithms seem to overwork the processor) and avoid the iLBC codec. If you look at the benchmarking for pjsip on the pjsip site you can sort of see where the hard work is distributed across the stack. On 15/09/2009, at 12:12 AM, Nikolay Popok wrote: > 1.
