I recommend that Sonic enable *61 call blocking as is offered by ATT. My former ATT Uverse service provided the *61 feature which enabled me to block a robo telephone number that had bypassed NoMoRobo. After hanging up on the robo call, I simply dialed *61 and that robo number would be blocked. Blocking numbers in one's Sonic account is very cumbersome, and difficult to achieve. Thank you. Tom.
