Add #31# to Phone number in Mobility
we have the requirement to add the prefix #31# to any phone number in mobility when the user clicks the number to call it.
This prefix will hide the phone number for this call from the customer.
Switching off the caller id in general on the phone (all calls) is not an option as the phones are also used for regular calls where the number should be provided.
Changing all phone numbers in the data is not an option as the data is also used in manage .
