I know InnoCaption is continuing to work on implementing stronger spam controls and already has a spam filter in their app to help.
Have you tried using it? It’s accessible by going to Settings —> Spam Call Filter —> Enable
I use InnoCaption. What I do is give people my cell phone as I have call forwarding, so the InnoCaption number seamlessly transfers a call to my native cell phone number.
I believe InnoCaption can change the phone number they have in your account so you have a number where it’s less likely to occur.
The problem is that spam has increased so much so quickly so my cell phone number is spammed all the time.
I would definitely recommend using call forwarding with InnoCaption and instead give people your native cell phone number. This way, it’s just one number for both calls and texts. Plus, if the InnoCaption number is receiving a lot of spam, then it could be changed without you needing to change your number.
I have found InnoCaption support to be amazing.
I would also recommend Hiya, as it shows caller ID and can sync with your phone block list so you can use either Apple or Hiya to block spam numbers.
