Doesn't that describe at least 80% of phone calls? I know that here in
the US 99.99% of our customers have POTS analog telephone lines. The
only ones who don't are commercial accounts that have T1 or PRI
service, and maybe one guy who has a BRI for some unfathomable reason.
Cell phones are also typically digital as well. A commerical T-1 echo
canceler hardware device is not usually cheap, but I'm told they are
very effective.
