Hi, I created an application based on pjlib on Symbian OS and have some problems with the sound. The SIP session is OK but during the media session the sound is interrupted at the caller side and the destination has an echo (during of all conversation) and the sound is interrupted also. I did the tests with Nokia E71 on 3G network. Do we need a 3G network? What are the minimum requirements (Phone hardware: processor, memory and others) to have a good quality of sound? Thanks, George. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20090317/d34eba8e/attachment.html>
