Thank you for your insight. It was really helpful. You suggested if I wanted to reduce the transmission jitter. Yes, that is exactly what I wanted. But installing a master port between the conference bridge and sound device doesn't seem to have any effect in this case. The transmission jitter still remains the same. I am attaching snap shots of the forward (pjsua) and reverse (some other sip phone) RTP stream analysis using Wire Shark. It seems that during transmission the delta for the forward stream fluctuates in contrast to the reverse stream whose delta and jitter remain pretty much the same. Thank you for your time.
