1. You aren't saying you want to make a substitution (so add 's')

s/\(\)/g

2. You aren't saying what you want to substitute them with (so add /)

s/\(\)//g

3. You are trying to match "()" rather then "(" or ")" (so wrap them in 
brackets and stick a | between them)

s/(\(|\))//g

So:

$ perl
$foo = "+44 (7777) 123456";
$foo =~ s/(\(|\))//g;
print $foo . "\n";


Outputs:
+44 7777 123456
