Hi Benny and pjsip community members, I have loaded Fring and made a skype-out call on N82. I also experienced similar (~1sec) voice latency. One speculation might be that Fring is also being negatively impacted by the Audio Streaming API. Hope this piece of information may bring some value to those who are working on this problem. Benny, regarding your below comment on jitter buffer optimization, would you please tell me since which SVN version (or date) has it been integrated? (I would like to know how latest is latest enough.) Alex Leung. -----Original Message----- From: pjsip-bounces@xxxxxxxxxxxxxxx [mailto:pjsip-bounces at lists.pjsip.org] On Behalf Of Benny Prijono Sent: Monday, April 21, 2008 6:38 PM To: pjsip list Subject: Re: PJSIP on Symbian,any pointers for tackling the audio optimization challenge?

Frankly I've little idea on this, but Yohannes (on this list) had suggested to me that it may be due to the audio backend that we use (the Audio Streaming API) and we may be able to get better latency with using Audio Proxy Server API instead. Unfortunately we haven't had time or resource to experiment with this so this has to wait until we're done with version 1.0. But it may help if you use the latest version of PJSIP from the SVN trunk, since we've done a bit of optimization in the jitter buffer to reduce the latency. > Anyway, I would like to express my gratitude for the progress pjsip > has made so far on the symbian platform.
