Hi Alex I am not sure if there are any specific recommended values, it depends a bit on your network conditions and use case. In the past I have encountered cases where audio was coming in very rapidly after a radio state change in 3G networks and in a scenario like this or in a mobile network with a lot of jitter, you might want to increase these params a bit. You can modify them as you please, just follow the limitations described in pjsua, the values should be in msec when configuring from pjsua level, if you are working with the jbuf directly it might be in frames. I have had cases where we used several seconds as max values so there should not be any restrictions, it is more a matter of how much latency you can afford to introduce etc. /Johan ________________________________ Este mensaje se dirige exclusivamente a su destinatario.
