So Id like the ability to block incoming calls and/or SMS. The Teams client does allow individual users to block PSTN calls. Individual Teams users cant manipulate this list. This inbound call blocking feature only works on inbound calls that originate from the PSTN and only works on a tenant global level. In addition to possibly being disabled, ATH might not actually end a call but just change mode in an alternating call, although that is a rather obscure feature probably being phased out in most networks today. In some cases they are going quite insane, and refuse to believe that they have the wrong number. If a match is made, an incoming call is rejected. So if you just store your white list in your modem's phone book, you might possibly not need to do anything more.Īs a last alternative you might try to just start a new outgoing call (possibly to a number that does not answer (your own number ought for instance to work)), hopefully discarding the incoming call (or maybe it changes state to waiting then?

How to detect and reject incoming calls in flutter even if the app is in background.
