A month or so ago, I received one of those educational emails from Voip.ms regarding caller ID filtering and how one could turn on STIR/SHAKEN filtering. So I created a filter that required STIR/SHAKEN compliance as a means to hopefully reduce the spam calls that I received. After enabling it, I didn’t think anything of it and was happy that I stopped receiving spam calls. But I then started thinking about it further this past weekend after realizing that I haven’t received ANY calls in about a month. So I then tried calling myself with my T-mobile cellular line and got a busy signal. I tried my wife’s work cell which is on AT&T and I tried my work cell which is on Verizon. None of them went through. I checked online and T-mobile states they are 100% STIR/SHAKEN compliant. I tried it again by relaxing it to the 2 other levels (B/C), and I still was not able to get through.
I setup the caller ID filter as described in the wiki. DID Number > Caller ID Filter > create a new filter, which I applied to all DIDs (I only have 1). Are there other steps that I need to take to make this work?
