IPX and voice over IP

[rkmorrow]

I have just taken over a router that has ipx and voice over ip configured and I had some questions about the config. I was told the router is not configured but that the kentrox csudsu was configured to segment the channels for voip.Thanks for any input.

the config is as follows with questions next to encapsulation and bandwidth:

Your issues:
IPX over PPP is quite commonly used.
The bandwidth command just affects the routing protocols in
use, it has no affect on the interface "speed", so you have a valid contention here.
IPX Rip and IP Rip are not going to worry about the bandwidth of the interface, and those are your only routing protocols
so I would imagine that either at one time IGRP/EIGRP was in use and some more sophisticated work was being done, or theconfiguration was just being accurate to let you know the circuit's cap.
Some of those locations sound very familiar to me...
