Thanks for your kindly response, Benny.

I tried with PCMU. In my platform, a ARM 9 processor, simple_pjsua is
required almost 95% CPU utilization. The only solution seems porting
encode/decode to DSP. Does anyone have better suggestions for me??

( I had complied with http://trac.pjsip.org/repos/wiki/audio-check-cpu
to decrease my CPU utlz, but it's useless)
