Hi all I am using PJSIP on Windows Mobile PPC/SMP phones, and I noticed that when making a VoIP call there is a substantial echo & delay heard byboth sides, but mostly on the destination side. I have already set the following parameters: media_cfg.ec_tail_len = 0 media_cfg.no_vad = true media_cfg.quality = 10 I would appreciate your advice on this. Thx Remo -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20100128/b93ae502/attachment.html>
