Hi Benny, I update my application with the latest version the "trunk pjproject- 1.1" and continue to test on Nokia E61. As you suggested I changed the codec priorities in a way that GSM had highest priority (in function "pjsua_media_subsys_init" priority value = PJMEDIA_CODEC_PRIO_NORMAL +4 (132)). The sound was acceptable on the caller side but on the callee side continue to be stuttered, disrupted and instable. Also I tried the others codecs (iLBC, Speex/8000 and Speex/16000) in the same way but didn't see any improvements. Do you have any suggestions or ideas? We don't want to use Nokia APS (Audio proxy Server) for the moment, because it needs a publisher ID. Thank you, George. _____ From: pjsip-bounces@xxxxxxxxxxxxxxx [mailto:pjsip-bounces at lists.pjsip.org] On Behalf Of Benny Prijono Sent: Friday, March 20, 2009 2:32 AM To: pjsip list Subject: Re: Pjlib on Symbian 2009/3/19 George Evi <george.evi at ctcinc.ca> Hi Benny, Thanks for your response. The flow of sound is disrupted on both sides (caller and callee voice reception). You can hear the sound but the words are not completed and on the callee side the voice is metalique (like a robot speech). The latest tests I made were done with Nokia E61 (S60 3rd edition -mr) connected Wi-Fi and I expected to see some improvements but voice stilled disrupted. I'm using iLBC as codec (1st priority) and UDP transport. Aha, that's probably the reason. iLBC is heavy, I don't think the device has enough processing power to run it [2]. Try with GSM or Speex. Alternatively, consider using APS-Direct [1], available in pjsip version 1.1 now downloadable from the website. APS-Direct uses handset's native codec and it supports iLBC, AMR, G.729, and G.711. cheers Benny [1] http://trac.pjsip.org/repos/wiki/Nokia_APS_VAS_Direct [2] http://trac.pjsip.org/repos/wiki/PJMEDIA-MIPS -------------- next part -------------- An HTML attachment was scrubbed...
