Hi , we are using jain-sip for sip stack. For handling call control. For Media purpose we are using pjsip. For a single call it is working fine. when I started this library for conference , at that time voice is breaking. Suse Linux Enterprise edition 10. 64-bit machine. yamaha sound card. I had tested with pjsua demo, it was working fine with different call conferences. So , I developed Native library using C for Java. confsample demo code I have used to write my own library functions. Calls are connecting properly and voice also distributed equally to all calls. but the problem I am facing is breaking voice. please help me in this.
