//Initiate a call to a contact
public void initiateCall(String phoneNumber)
//Validate the phoneNumber
if(isValidPhoneNumber(phoneNumber))
//Use a communication layer method to initiate call.
communicationLayer.initiateCall(phoneNumber);
else
//Handle invalid phone number
showErrorMessage(“Invalid phone number”);
//Simplified example
//Check if the phone number is valid.
private boolean isValidPhoneNumber(String phoneNumber)
//Implement your logic to validate phone number.
return phoneNumber.matches(“\\d10”); // Example pattern, replace with robust validation.
“`
