Believe today's was the first call from this particular number, but the frequency of unsolicited calls from other 720-numbers has increased this month. I never answer these, or any other mystery calls, and the callers never leave messages. Works for me.
Frequently called. One time I answered there was no answer on the other end. Blocked and continue to reject calls from them, but much less frequent now, down to once or twice a month from the mutiple times a day it was at.
