Very poor audio quality

Hello,

I am new to al of this VoIP/SIP stuff so bare with me please if am talking
non-sense, or if i am asking trivial questions.

I am trying to integrate pjsip in an iPhone application  i am working on.
The iPhone runs on iOS4.3.3 and i am using PJSIP v1.10. I have managed to
get things working but for some reason i call quality is really poor with
lots of cracking noise. I am running the app over WiFi not 3G.

My question is what do i need to check/implement in order to improve the
quality. I know i will be asked to post code but the problem is i am not
sure which code is responsible of this. So I would appreciate if any one can
recommend which parts of pjsip i should consider in orde to achieve better
call quality.

Many thanks in advance
AF
