  To me, it's capacity.

  Jitter can cause audio drop-outs if the delay is high enough that the receiver considers the packets missing. Jitter buffers can help with this, but does not solve cases of very high jitter which can be caused by capacity issues. "If the jitter is so large that it causes packets to be received out of the range of this buffer, the out-of-range packets are discarded and dropouts are heard in the audio. For losses as small as one packet, the DSP interpolates what it thinks the audio should be and no problem is audible. When jitter exceeds what the DSP can do to make up for the missing packets, audio problems are heard."
