I have to be careful here as I auto-provison these devices and changes 
would propogate to every user.  Echo cancellation is off.  Do you think 
it should be on?

No but it is the same as other users who do not have the problem.  I use 
a SIP phone and a Cisco ATA.

I understand but some use cases just need it.

He does want to have an extension so that won't work.
