Pings are slow, then faster, faster, faster, then slow again, then faster... And so on in this cycle?

I'm trying to find out what's causing some odd slow downs of our Net access in the office. One thing I've noticed is that the ping times to one particular device (a PBX) are pretty odd. They always start off about 35 ms (already very slow for a LAN device), then 34, 33, 32 (more or less like this, sometimes it's not quite such a uniform decrease, but always with a downward trend), until it gets to about 3-4 ms, then bang, back to about 35 again. Then it repeats once again, 34, 33, 32, etc.
Does this look familiar to anyone? Does it mean anything? And why would this one device have such bad ping times anyway? Tracert confirms it's just a single hop away.
