Did you check the QOS markings? It should be COS 1 and be trusted. If not, then you could have large delays between RTP packets when the network is busy.

Did The max delta time is the time between packets. Max delta of 55.05ms can be an issue if the receiver is expecting the subsequent RTP packet sooner. It depends on the ptime, which I have seen at 20ms or 30ms. I suspect it is 20ms for your system because you have a good call with the max delta of 21.80ms, which it normal. If the receiver is expecting the subsequent RTP packet around 20ms, but it gets there a 55.05 ms then this could affect the audio quality if it happens frequently on the call.
I would check the QOS markings? It should be COS 1 realtime COS1/EF, and be trusted. If not, then you there could have be large delays between RTP packets when the network is busy.
