So I know this is a fairly simple question, but I can't seem to find a good answer to it. I have a DID which is getting hit fairly hard (or at least for me, about 1-3 calls per day) with telemarketers from non 1-8XX numbers. However there are only a handful of numbers that call day in and day out. So naturally I would just like to block them so my phone doesn't ring and I don't get billed for a call.
I'm looking to send a SIP/404 or some other non-answer response-- not send them to voicemail or another recording. I don't really care about logging or anything like that, I just would like to be able to add (or remove) a number fairly easily so I can cut down on unnecessary calls.
Everything I find seems to be either too complex or too simple (only one blocked number) and I can't find a good medium. Hopefully someone else will have better insight! I am using Asterisk 1.6. Thank you!
