Spam Caller: +1 805 637 7243

Here's what may be happening: Scam callers use a service like Spoof Card. This service allows the scammer calling you to provide two things: (1) the phone # they are calling (your phone#), and (2) the phone # they want your Caller ID to see (805-637-7243, which is TMO's Voicemail #).  Anonymous callers using this method are able to leave you an unwanted message without you ever hearing your phone ring and without a trace on your Recent Calls. For TMO customers, this 805-637-7243 is the T-Mobile Voicemail service which is the same as pressing and holding the 1 key on your dialpad (observe the phone # that is called when you do this). When they call using this Caller ID #, the call on the TMO network goes directly to Voicemail. Some businesses use this technique and it tells you a lot about their integrity.

MESSAGE TO T-MOBILE: It seems that T-Mobile engineers should be able to identify when a customer's an incoming call is coming from this 805-637-7243 # and if so, simply dead-end the call instead of sending it to Voicemail. The problem is then solved.
