I solved the problem. There problem was in old portaudio version that comes with pjsip. I downloaded the last stable version pa_stable_v19_20111121.tgz , November 21, 2011, SVN rev 1788. and replaced /third_party/portaudio with it. To build with this version we should remove line with pa_skeleton.o in /third_party/build/portaudio/Makefile #### Patch data follows #### diff -c 'Makefile.old' 'Makefile' Index: ./Makefile.old *** ./Makefile.old Tue Jul 29 15:42:20 2008 --- ./Makefile Sun May 6 00:04:33 2012 *************** *** 15,21 **** pa_debugprint.o \ pa_front.o \ pa_process.o \ - pa_skeleton.o \ pa_stream.o \ pa_trace.o --- 15,20 ---- #### End of Patch data #### Benny, can You update pjsip to use the last stable portaudio version?
