I get a lot of spam calls. Even though they show as blocked on the cellular phone, they ring on the Home Extender. They do not ring on the cellular phone.
Hi @nylesn and welcome to the Community!
This experience is explained by who is doing the blocking on your cell phone. If it’s Google via their Phone app or if it’s a number you previously blocked using the Phone app, those are not synced with the Extend Home adapter. In that sense, your experience is as expected.
Republic does offer call blocking via the Republic app on your cell phone. Presuming that’s engaged, call Republic blocks are blocked on both the cell phone and Extend Home adapter. More on call blocking via the Republic app is linked here:
