Frames discarded and no voice at the beginning of the call

[shaydvir]

Hello guys,

I experience one annoying issue for quite awhile now, and thought to share the problem here: Whenever I try to initiate a call and the other side answers the voice is cut off at the beginning of the call, sometimes the first 1-4 seconds and sometimes it reaches 10+ seconds. Rarely it works fine. Worth-to-note that: - It happens mainly on Samsung devices, Phones such as Xiaomi, One Plus and Sony works good.

- I think It’s related to CPU usage, I tried to compile it with switch board and it worked good but with horrible sound.

- I tried several codecs, and it acts the same (G729, Speex, GSM).

- I noticed that the Jitter Buffer changes correspondingly, I saw this line in the logs: Jitter buffer starts returning normal frames (after 102 empty/lost)

When the number is below 30 there is no cut at all. You can hear the first "Hello" of the other side, but when the number is somthing like 80 or 100 the other side can say "Hello" one or two times but you wont hear that . this is not a delay, the voice is cut.

I'd be happy to get help with this. How to prevent the audio cut? thank you all!
