We get that with our Bell Canada PRI only on certain (local) exchanges.  I'm 
not exactly sure what is causing it but it's been a problem since we 
installed the PRI.

I doubt it, the echo can seems to be working just fine, but in your case (and 
mine) it seems like it must be getting disabled.  I must admit it's been a 
while since I've dove into this problem, but if you execute dmesg -c on the 
asterisk box, make a call that will echo, and execute dmesg -c again, is 
there any mention of "echo canceller disabled on channel 5" in the resultant 
output?
