at what point exactly the connection fails? Does the remove machine 
detect ringing and try to receive the call? If this is the case, it is 
possible that this is a modulation related issue. You could try to use 
each of the following init. strings on the machine which is dialing 
until one of them fix the problem.

AT &F W1 +ER=1; +DR=1; +MS=V90,0
AT &F W1 +ER=1; +DR=1; +MS=V90,1
AT &F W1 +ER=1; +DR=1; +MS=V34,0
AT &F W1 +ER=1; +DR=1; +MS=V34,1
AT &F W1 +ER=1; +DR=1; +MS=V32B,0
AT &F W1 +ER=1; +DR=1; +MS=V32B,1
AT &F W1 +ER=1; +DR=1; +MS=V32,0
AT &F W1 +ER=1; +DR=1; +MS=V32,1

If the remote modem is unable to detect the ring, please try with 
Windows on the same machine to see if it is able to detect the ring or 
not. Please report the result of this test to support at linuxant.com.
