Hi All,
Need advice on below requirement in TCC outbound file. 
Requirement:
Remove Special characters from primary phone number
And
If the primary phone number is more than 10 digits and the first digit is not a 1, then a NULL (empty) value should send
Or
If the primary phone number is less than 10 digits, then a NULL (empty) value should send

Examples:
1. If phone number is 98765-432*10 results should be 9876543210
