Ahh okay, I saw on some XMPP clients feature grid that Cheogram didn’t have those features, good to know that it does.
No TLS/SRTP for SIP phones is really rough but I understand supporting SIP hardware isn’t a primary goal for you guys. Maybe I could have calls also ring my existing provider for when I want to answer them on my hardware device? But then I’d be paying double per-minute rates, and I’m not sure how outbound calling would work.
As far as spam filtering, not sure what my provider does by default, and some numbers I’ve had with them have been spammier than others, but with a recent spammy one, I dug around in their control panel and was able to make a rule to direct calls with a STIR/SHAKEN attestation level below X (my choice) straight to voicemail, or do whatever else with it. In that case I dumped all level C calls direct to voicemail and spam calls immediately dropped by about 90%. They also have the ability to do this with caller ID blocked calls, and ones without valid North American caller ID. And they have a “press 1 to connect” feature but I haven’t tried that one yet.
I think they also have some always-on secret sauce spam filtering similar to whatever Google Voice has, but I don’t really remember details and a cursory search didn’t turn up much. I originally switched from Voice after reading about it, though.
But, there’s no way to tell how many spam calls it’s blocking because there are no logs for that. So I don’t know if, on my spammy number, it’s blocking 3x the level C calls which actually made it thru, or what.
I appreciate you taking the time to talk this over with me. Spam filtering is a must-have for me because if I get too many spam calls ringing thru, my brain will assign all calls to the Noise category, at which point the phone becomes much less useful to me.
