Hi Benny

I think there is a buffer bug in pjmedia capture that makes sound problem after several hours.

Use pjsua-i386-Win32 sample using Directsound and set
snd_auto_close_time = -1 // disable
Then make a call to activate sound.
Wait 36 hours.
Call again from pjsua-i386-Win32 sample. You hear on other site drops. 
It seams that the Directsound capture buffer will make problems after several hours running.
