Hi, I have been studying voice quality using pjsua and came across a nice tricky "feature" of pjmedia's jitter buffer. Either using progressive discard or not, in the begging of the call, some frames are discarded unnecessarily (20~25). It seems to happen because there is a big number of frames waiting in the buffer right before the jitter buffer's state changes from initializing to processing. All of this, however, does not happen all the time. To be more specific, if pjsua A calls directly (peer-to-peer) to pjsua B, this event can be noticed only in A. I have been trying to find a nice way of minimizing this effect but have not found anything worth until now. As I am not exactly an expert in pjsip, I decided to ask around here if this kind of discard has been noticed before. Should I open a ticket for this? Thanks! -- []'s Andr? de Abrantes
