I have a couple of strings like:
Unassigned Number (1) 32
No Route To Destination (3) 12
Normal call clearing (16) 2654
User busy (17) 630
No user respond (18) 5
User alerting no answer (19) 16
Call rejected (21) 3
Destination out of order (27) 1
Invalid number format (28) 32
Normal unspecified (31) 32
No channel available (34) 2
Temporary failure (41) 11
Switching equipment congestion (42) 4
Resource unavailable unspecified (47) 2
Bearer capability not authorized (57) 73
Incomp. dest. / Non-existent CUG (88) 1
Recovery on timer expiry (102) 2
Interworking, unspecified (127) 5
I need to get:
Error code (value in brackets) - Value - Message.
My actual problem is i can't get how to include space, comma, slash. 9 1168

The following solution is 100% regex-free :-)

My pattern now is:
(?P<var1>[^(]+)(?P<var2>\d+)\)\s+(?P<var3>\d+)
And i expect to get:
var1 = "Unassigned Number "
var2 = "1"
var3 = "32"
I'm sure my regexp is incorrect, but can't understand where exactly.
Regex.debug shows that even the first block is incorrect.
Thanks in advance.

Probably you have some escaping problem. The substitution:
re.sub(r"^(.*)\s*\((\d+)\)\s+(\d+)", r'\2 - \3 - \1', row)
does the required job (where "row" is one of your lines)
To match a special character, such as "(", you need to escape it with a
"\", because it has a special meaning in the regexp syntax. Because "\"
is the escaping mechanism for Python strings too, you better use raw
strings to specify the pattern.
Other special character/groups matching patterns, such as "\s" to
specify whitespaces, are documented, together with everything else you
need, at http://docs.python.org/lib/re-syntax.html

You are missing \( after the first group. The RE should be:
'(?P<var1>[^(]+)\((?P<var2>\d+)\)\s+(?P<var3>\d+)'
Great thanks.
You post helped me so much!
My resulting regexp is:
"(?P<var1>^(.*)\s*)\(((?P<var2>\d+))\)\s+((?P<var3 >\d+))"

"(?P<var1>^(.*)\s*)\(((?P<var2>\d+))\)\s+((?P<var3 >\d+))"
Notice that this way you are including trailing whitespaces in the var1
group. You may want to put the "\s*" outside the parenthesis.
mmm... in this case you should make the ".*" in the first group
non-greedy. r"^(?P<var1>.*?)\s*\(((?P<var2>\d+))\)\s+((?P<var3 >\d+))"
does the job.

I'm sure my regexp is incorrect, but can't understand where

Break it up using verbose notation to help yourself. Also, use
more helpful names. With names like var1 and var2 you might as
well not used named groups.
r = re.compile(r"""(?x)
(?P<error[^(]+ )
(?P<errno\d+ )
\)
\s+
(?P<lineno\d+ )""")
This way it's clearer that there's a \) with no matching \(.
