My best guess is that `libphonenumber` just isn't perfect ... :-)

Hello all

we are using the phonenum_match_cn function to detect valid phone numbers, but seems there are some numbers like 576015145834 which are no detected as valid ones, 
$phn(ani=>valid) --> 0
$phn(ani=>ccname) --> <null>
$phn(ani=>cctel) --> 0
$phn(ani=>error) --> Invalid number

but using 
https://libphonenumber.appspot.com/phonenumberparser?number=576015145834&country=CO seems it gives a valid result

Validation Results
Result from isPossibleNumber() true
Result from isValidNumber() true
Result from isValidNumberForRegion() true
Phone Number region CO
Result from getNumberType() FIXED_LINE

we are using kamailio 5.4 and libphonenumber tag v8.12.30 (also tested v8.9)
the command is used with 'ZZ' cnc and passing the number with +

maybe we are missing something in the configuration/setup?
thanks and regards
david
