[ale] Need some modem help

I've been racking my brain for ours on this and am exhausting my years 
of modem experience.


I've created a modem bank at Peak 10.   I have device installed calling 
this bank.   One of these sites has 6 locations around NY.  When I call 
them I get a connection as fast as I can get. When they call me their 
modems can not sync.  All modems are the same.  Conexant USB 0529:1340 
USB modems. The only way I can get them to sync when calling me is to 
have mgetty use the initstring AT+MS=v32,1.  This forces a 9600baud 
connection.  Unfortunately this means all other modems are forced down 
to that speed when they call.  I can't modify the initstring on the 
device (yet).

What I'm trying to do is figure out what could be going on that allows a 
fast connection to those modems, but a reliable reverse connection is 
not possible.

Any ideas?
