Robikhun,
As you certainly noticed, the Init lines all start with AT.
Actually you could prefix each command on the line with AT as for example:
Init2 = ATQ0 ATV1 ATE1 ATS0=0 AT&C1 AT&D2 AT+FCLASS=0
which is clearly a waste of time.
For an introduction to Hayes AT commands, please read
http://en.wikipedia.org/wiki/Hayes_command_set
Do not miss the remark about Windows
Next, specifically for the +MS command, read
http://www.xtra.co.nz/help/0,,4155-2131674,00.html
Finally, do not miss Marv's instruction to always have the
+MS command as LAST definition in the LAST string (since you are one of
the few to rightly ask why: because other commands may reset the speed
limits).
The whistles which you hear when starting the modem are the negotiations
about the best speed for the two connected modems.
They do not always succeed, and IN PARTICULAR if for whatever reason any
segment of the telephone line is wireless such as radio instead of cable
to reach small remote areas such as islands.
The difference between the Linux and Windows modem speed setting is most
often due to different driver code.

If this is because low quality of phone line why using Windows this
problem didn't appeare?
$ sudo gedit /etc/wvdial.conf

Robikhun,
Since the dialout worked last week and is not reproduceable, it is
likely a phone line quality problem.
Read the wvdial.txt
Try adding to the end of the Init2 = line , the
+MS=90
as substittute for a default +MS=92
If this does not improve the situation. try instead +MS=34
