maybe it's for resample problem.
In you .asound.rc is 8000 rate. Do you use in pjsip application same rate?
if not pjsip try resample it. by quality options is select algorithm
in pjsua its options --quality ..i dont know now right path but when you look
at PJMEDIA_RESAMPLE_IMP in source you find all what you need about it.
