Call Blocking List

This app uses the ability of iOS10 to block phone numbers, so they are rejected by the iPhone.

The numbers to be blocked can simply be stored in the app with an optional comment. The comment is only displayed in the app, to know later why you want to block this number.

You can also block phone number ranges. Simply replace up to 9 digits with question marks at the end of the phone number. So 123456?? will block all numbers from 12345600 to 12345699 (limit to four ? per number - because that will block 10.000 phone numbers)

It is no longer necessary to create a contact, which is then blocked - but the contact list "inflates".

*** Share Extension ***
When you share contacts with the app (for example, from the Contacts app or from other apps, by vCard), you will be given a list of the phone numbers from that contact which you can select to block and put an optional comment for the reason - without having to open the Call Blocking List app itself.

*** API ***
Third-party apps can pass phone numbers, including comments on blocking via URL schema.
To do this, you need only the URL sperrliste://add?n=xxxx&c=yyyy
Where xxxx is the phone number and yyyy is the comment with which the creation dialog is presented.

Note:
If your network operator is routing non-assignable calls to a VoiceMail, this will be applied to blocked calls, as blocking is only on the phone, but not on the mobile network.
