Yes, get another 9600SA.  Those modems have a horrible problem with
quality control and component failure.  If you can get a good one,
they work well, but that's not as easy as it may sound.

Two of the lines here on crash have 9600SA's on them.  So far, to get
two that work consistently, I have gone through a total of seven (7!)
modems.  Everything from failing to answer, failing to connect in V32
modem, static on the line when the modem picks up, long pauses during
MNP, etc., etc.  One bizarre thing after another.  Right now, I have
two that do pretty well (and have ROM version 1.26 in them).  For how
long is another story.

Try another one -- chances are your symptoms will go away, or at least
change.
