Block calls by CNAM (CallerID Name) on OBI200?
Darv:
Is there a way to block calls by Caller ID Name (CNAM) on the OBI200?
I've also been trying to find how to block thousands of numbers, and usually asterisk/freepbx is recommended for these features but I think that is overkill and quite large and hard to install and maintain.
If Obi can't block by CNAM is there a simple script that could be used as a middle proxy to act as a call blocker (based on number or name) between voip.ms and the Obi200?
I see there are many "sip proxy" scripts but I'm not sure if that is what I would need for this use case. I'd like the smallest, most minimal thing to use to block calls and log them.

Please do not start a new discussion on the same topic. You already have a discussion going on here:

No, you cannot block calls by CNAM. It would be a useless feature, given that most spam calls use spoofed telephone numbers and either no CNAM or the CNAM of the spoofed number. Many calls from legitimate and from spammer numbers are using mobile phone numbers, and some carriers send a generic CNAM, such as "WIRELESS CALLER", which would not differentiate between a "good" caller and a "bad" caller.
On the other hand, if you have 1000 enemies, and you know the CNAM for each number, then refer to your original discussion.
Darv:
The feature to block by CNAM was different than the feature to block unlimited numbers by Number, hence the separate posts. The threads can be merged if they are too similar.
I've used CNAM blocking for years so it isn't useless, but I am not sure how to easily implement it on the Obi. Many survey companies use the same CNAM. Having the feature doesn't mean anyone would need to use it, nor that it would be appropriate to use for all Names, only that it was available as an option. I do not have "enemies", but I have accumulated a list of nuisance calls (numbers and names) that I'd like to continue to block.
SteveInWA:
There simply is no ability to block by CNAM.
Lavarock7:
Are those blocked numbers often calling or is that each time you got a spam or telemarketer you blocked them?
I ask because there are better ways of blocking many of them, like NOMOROBO. I also use Voip.Ms and their 'automated attendant' to block most spammers/telemarketers. A simple message "Thanks for calling, press 3 to reach me' works wonders.
Yes, there are SOME people still using rotary dial and you can default them to a timeout that still gets through. Some robo calls hear a long message (simulating an answering machine) rather than a brief one (like a 'hello') and hang up.
