Let's say...I call this person and it rings one time (about 5-10 seconds) and sends me directly to her voicemail. I then call again with *67 (means you block your number when calling out), her phone rings 30 seconds and goes to the voicemail. I know that she is not with her phone at the moment. I test again and use another cell phone to call without *67, it rings for 30 seconds and goes to voicemail. Does it mean she blocks my number?
