Can we use this to auto-block them? More generally, can we use data about the call to do some spam filtering?
EG: listen to the first sec of a call and try to measure the amount of noise, the amount of lag, or if there is any feedback at all (like you would have if you were speaking with another human and not with a robot). Then use that to either kill the call or make it sound.
- daurnimator 10y agoBut it's only after answering the sound happens. To filter based on it you'd have to answer calls before the end user's phone even rung.
- Turing_Machine 10y agoThat doesn't seem to be all that difficult, conceptually. Have the system pick up the call (without generating an audible ring for the user) and listen for the block. If it hears it, buh-bye. If it doesn't hear it, then ring the phone for the user, while also playing back a simulated "ringing" signal to the caller, so the caller was unaware that the call had actually been "answered" already.
- Splines 10y agoConceptually simple, but "answering" the phone with a simulated ring has a lot of side effects. For example, voice mail might be broken. I'm unfamiliar with the exact specifics of how phone calls are routed, but you might be able to get away with more if you own the phone switch (e.g., self-hosted asterisk or something like that).
- r00fus 10y agoI have to be that guy to ask: Does anyone use voicemail anymore? My family doesn't even now that they all have smartphones. No answer? Followup SMS with basic question. Done.
- ashitlerferad 10y agoFollowup MMS is the best voicemail method.
- daurnimator 10y agoIndeed. e.g. billing will start when the call is answered.
- kevin_thibedeau 10y agoYou have Lenny answer and then "transfer" the call to you after confirming they are legit.
