Hello, I am experiencing 1-2 seconds of initial jitter when I make a on a 3g connection. My application is an iPhone application using pjsip 1.0.3 compiled in conjunction with iPhone OS3.1.2. The initial jitter is only heard by the recipient I am calling from the iPhone application. After the 1-2 seconds the jitter clears up and the call sounds just fine. I have tried decreasing the codecs quality setting in order to drop the bandwidth intensity as well as using the jitter prefetch buffer. Both have had no effect. Was hoping that trying one of the more recent versions of pjsip might yield better results. At the moment I can get pjsip 1.5.5 to compile and connect calls on the iPhone, but can't get the audio to work. If anyone has some insight on the what might fix the initial 1-2 second jitter lag or getting pjsip 1.5.5 audio to work on the iphone please feel free to reply. _____________________ Brad Sweeney brad.sweeney at gmail.com
