Hi I've been working on a softphone application with pjsip on a Windows Mobile 6.1 Professional phone, Samsung Omnia i900. I've been testing with X-Lite. Overall it works great but there's a lot of latency on receiving audio, generally over 600ms, sometimes 800ms. Sending audio has almost no latency at all. I've even tried between two X-Lite softphones and theres no latency, so it's not the network (wi-fi for both mobile-pc and pc-pc). I've tried several configurations but I still haven't been able to reduce much the latency. My objective is between 300ms and 400 ms. My configurations for pjlib and pjmedia are in attachment. I'd appreciate any help if possible. Thanks in advance -------------- next part -------------- A non-text attachment was scrubbed...
