Yes, but you can determine if the packet is missing due to packet loss or if
it is missing due to vad by looking at the RTP sequence numbers and time
stamps.   I agree that the first step to getting this properly working is to
get a better jitter buffer as you have to buffer to a degree to examine the
sequence numbers.
