i use the last version, and download form http://svn.pjsip.org/repos/pjproject/trunk ,data:2008-5-14.
   
  i think it may portaudio problem, because i set pjsip work on Directsound (define PJMEDIA_PREFER_DIRECT_SOUND     1),  the cpu very low , < 3%. but Directsound work not stabilize, when  A speak loudness then continue print :"Underflow, buf_cnt=****, will generate 1 frame" , can't hear anything.

We also experienced that speex encoder may cause CPU increased
significantly when silence occurred (not sure why), and this is
already handled by pjmedia since few months ago. So which version are
you using?
