Hi, You could try to set min_prefetch in the jb to 1000. /Olle -----Ursprungligt meddelande----- Fr?n: pjsip-bounces at lists.pjsip.org [mailto:pjsip-bounces at lists.pjsip.org] F?r Kevin Yu Skickat: den 4 februari 2012 19:55 Till: pjsip list ?mne: Re: [pjsip] PJSUA play back delay Thanks for the quick response. No. My platform is IOS 5 on iPhone 4S. I also tried to increase the size of de-jitter buffer by doing jb_max=1000. I didn't see the 1 second delay either. What should be my best practice when it comes to put artificial delay into the audio stream? Thanks again.
