Thanks a lot. I think you mean "you should not need ...". So, echo cancelers in PRI cards are primarily used to cancel echo for the far end over PSTN. Assuming my end points have proper echo canceling of course.

So, if I'm using headsets and/or good IP phones I would not need echo canceler?

I cannot see how latency could introduce echo if there is no analogue "hybrids" path involved!!

Sure. But, as I mentioned in my question, the echo canceller of the IP phone should remove it. It does not make sense to fix the echo after passing through the phone and PBX's jitter buffers. It could be even worse if there is codec conversion.
