Note the comment in the statement that says "other then ... trunks".
Full agreement that most channel banks will handle echo cancellation,
impedence matching, etc, very well. They've been doing it for years.

The comment was oriented towards using a channel bank to connect analog
phones to *, and was not intended to start another thread, flames, etc.
And, we've all seen the discussion relative to the cost of sip phones
vs analog many times over, use of left over slots for phones, etc, etc.
If you have a specific case where that makes sense for you or your 
customer, knock yourself out (that would be the "some do" part). 
No need to rehash the "I'm cheaper then you are" discussions again.
