Not necessarily: it depends upon the route taken by calls from your
exchange to the terminating exchange/telco: if, for example, you are on a
London exchange, there is every likelihood that the route to, say, the
COLT Ascends, will travel over a different piece of cabling from that to
the Energis USRs: moreover, many of those junctions in the erstwhile LTR
are old and noisy.

Depends upon how you've configured your modem: it is possible to set them
up such that they refuse to negotiate downwards...
