Hey I have serious delay problems in my VoIP network I'm using/developing a pjsip based UA on a PC which calls a conference server (server is not based on pjsip) and I experience 300-500ms delay in the conference on the server. I have narrowed the problem down to my sound card which is "bursting" packets in bursts of 3 packets at a time. This means when I'm using 10ms frames the jitter introduced by the sound card in the PC is 0.01-30ms resulting in the adaptive jitter buffer in the conference server growing large very fast which of cause introduces a unacceptable delay. Now to my question :-) Is there any way of controlling or eliminating the bursts from the sound card when using pjsip? ...or do I really have to buy new and better sound cards for all the PCs in the network? Hope for some good feedback. Regards Jacob
