Actually, all MNP modems I have seen allow the MNP to either be made
automatic or switched off.  There may be some checp brand which doesn't
do this under software control, but I haven't seen it.  I just turn MNP
off when dialing certain systems.  I had to diddle my dialer a bit, but
the result is worth it.  The problem only occurred with a few system
which don't speed detect reliably when called with any modem, so I don't
see that this is a problem solely with MNP.  From the number of postings
on this topic in the last few months, I suspect that there is a general
problem with speed detect on some systems. 

I run into both MNP and non-MNP modems without problems.  Perhaps as
someone else suggested you might care to try another modem brand.
