How to Block or Stop Spam Calls, Text or Fax in My iPlum Account
1. How does iPlum help protect my business communications?
iPlum is designed for business communications with security and privacy controls that help protect your information. iPlum does not use your business communication content for advertising. iPlum also provides tools and safeguards to help users manage unwanted and spam communications.
2. How spammers usually work for calls, text or fax?
A common trick is to "Spoof" any random phone number in an autodialer and call thousands of users hoping to reach some of them. There are many illegal autodialer applications available online which allow this behavior. The end user gets a "missed call" and when they call back that number, it reaches the real owner of the spoofed number who never placed the call at the first time.
A spammer would randomly configure a number on some 3rd party rogue application and start texting out. For fax numbers they try to detect for fax tones.
