In Android phones, Google uses a phone number blacklist database in its phone application to prevent calls from known spam numbers. Calls from numbers registered in this database do not go through to the recipient.
I have two questions regarding this:
1 - Is there an API available for accessing this blacklist database?
2 - We need a constant sender ID that is consistently blacklisted. How can we obtain this?
I would greatly appreciate support and insights from those who are knowledgeable about this topic.
