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

>>> print lines
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

>>> [int(line.rsplit("(", 1)[1].split(")", 1)[0]) for line in
lines.splitlines()]
[1, 3, 16, 17, 18, 19, 21, 27, 28, 31, 34, 41, 42, 47, 57, 88, 102, 127]
