Phone number allow + symbol at first position only with optional value
-
-
(hyphen) should not allow first and last position . But hyphen can allow in between number but maximum three hyphen can allow -
Space can allow in between numbers but continuously should not allow more than one space .. but single space allow n number of times
Example of allowed patterns:
+34 35 45-45-55-4

Example of invalid patterns:
