Provide Number Prefix Example Please

[dert]

Hi guys. This question might seem silly but I've seriously googled my fingers raw and can't find an answer to what should be a common question. When using the caller blocking functionality, you can block calls based on caller id. That works fine with specific numbers eg: 555-555-5555. The IVM instructions state you can also block calls based on a number prefix, which will block all calls starting with the desired prefix. To date I have been unable to get that to work however. I use semicolons to block all numbers that are known eg: 111-111-1111; 222-222-2222; etc. But when I try to block all of the 888, 800 numbers, I can't get it to work. I've tried using %888%, 888*, +888, etc but nothing stops all numbers starting with 888, IVM just ignores my entries and lets all the calls though.

 

So what is the proper usage of a "number prefix" to block all calls with that prefix. Please provide a specific example. Your documentation should probably be updated with that also to help out other folks like me.

Wait, seriously, NO ONE has an answer to this??? Is the functionality broken??

I don't see anything in IVM 5.04 Help about blocking by partial CID...at least not in the global settings...submit a feature request.

 

It can be cobbled together in a chain of startup OGM's and/or an external app that you pass in the CID and it returns a local variable (true/false) that you can then use to direct how the call proceeds (or not).
