Hi Nanang, thanks for the message again. It sounds like the last a few bytes are replayed. You are right. I was actually not sure if the way i am doing is the right way to play data in a buffer to a port associated with a call. Is there a better way to do it? thanks a lot Jessica > Date: Wed,25 Jun 2008 18:15:54 +0700> From: nanang@xxxxxxxxx> To: pjsip at lists.pjsip.org> Subject: Re: Play buffer to a port associated with a call> > Hi Jess,> > Could you describe more detail on "I can hear the audio, but it> doesn't sound correct", did it play correct audio but then continued> with previous audio? or audio was played slower/faster?
