Pull model is exactly what is needed for VoIP. Implementing proper RTP
jitter buffer on gstreamer push model with clock drift compensation is
really PITA.

Best way to implement jitter buffer would be to have the network side
pushing packets to the buffer and then the audio side pulling the
packets out of the buffer. This way the buffering can be easily handled
even in case of DTX.
