Any way to tell which router or link is introducing the delay?

C:\Users\xxxx>pathping 1.2.3.4

Tracing route to 1.2.3.4 over a maximum of 30 hops

0  2.3.4.5
1  7.8.9.10
2  3.4.5.6
3  4.5.6.7
4  5.6.7.8
5  6.7.8.9
6  1.2.3.4

If you consider the 60ms delay then it starts at router 4.

Most of our local equipment and links have a 0ms RTT.

VOIP might be getting delay or jitter.

I don't think we are actually dropping any packets.

What this is telling you is that there is a WAN link between hop 3 and 4, where the RTT jubs to 60 ms.

The 3ms jump is most likely between your router and the network provider's routers.  They would be close to each other,  but not in the same building, router.  Say within 100-200 miles.

Say you have something like:

Computer #1 <--> R1 <--> R2 <--> R3 <--> R4 <--> R5 <--> Computer #2

R1 would be in your building.
R2 and R3 would most likely be in located at the WAN network provider's close to you, but not in your building.

R4 would be located a few thousand miles away from R3.
