I have an Obi110 and I use it to monitor the caller-ID that comes in on my PSTN line. I already have a somewhat complicated inbound call route which implements a few blacklists to forward telemarketers for special handling.
Lately I've been getting a lot of calls at odd hours with no caller ID. It is not that they are coming through "Private" for cloaked caller ID, but rather a lack of caller ID. Is there any way to trigger on lack of caller ID and forward these anonymized (but not with privacy cloak) calls?
Ideally using the Obi's local auto attendant to prompt for caller's name and possibly make them enter a phone number to tag the call with and then ring through to the phone port, or forward through to a SIP or another number via GV?
I believe that some phone companies offer a service like this, but doing so requires removing the block that prevents any privacy-cloaked calls from coming through.
Implementing this feature would require knowing that there were enough PSTN rings to have received caller ID, but that there was none, and having a special string that could not come through caller ID. Fortunately the Obi developers are very smart and creative and might be able to come up with a solution!
