     1= Check that CPU Utilization == 
     2 
     3Some [wiki:sound-problems audio problems] are caused by high CPU utilization, so check that CPU utilization is not too high during the call. 
     4 
     5Remedy to lower CPU utilization: 
     6 1. Disable echo canceller (with pjsua, EC is by default enabled. You can disable it with {{{'''--ec-tail 0'''}}} command line argument. 
     7 1. If you're using complex codecs such as Speex or iLBC, try to use PCMU or PCMA (pjsua by default uses Speex/16KHz. Use {{{'''--add-codec pcmu'''}}} to use PCMU). 
     8 1. Use the release build instead of debug build (remove {{{'''-g'''}}} option from CFLAGS if you're using gcc). 
     9 1. Lower the sampling rate (by default pjsua uses 16KHz or 44.1KHz - 48KHz in Mac OS). 
     10 1. Close other applications that consume CPU. 
     11 1. As the last resort, upgrade your hardware!
