Matteo,

Occassionally we do encounter IPs whose servers are Linux hostile.
Perhaps you can find some local Linux users with a different IP, thus
to borrow their User/Password, to check your modem System on.

The NoEC problem typically has been encountered with Lucent DSP
modems.  I don't recall a prior NoEC problem with an external serial
modem.

In case there is an underlying noisy line problem,
try changing the Init2 line to:
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +MS=34
Also you should have a country specification.
Init3  =  AT+CGI=59
59 is the modem code for Italy.
