Thank you for that, but I am a little confused.
I assume you refer to the parameter InboundCallRoute on the “OBiTALK Service Settings” page.
When I deleted all the OBi-numbers the AA was bypassed just as you say.
I was referring to the thing on your OBi Dashboard
http://www.obitalk.com/obinet/pg/obhdev/owned/ in OBiTalk called
My Circle of Trust: Trusted Callers
If you are not using OBiTalk, that will change how things are done. In that case, you will modify dialing strings that say ":aa". That is more work, although it is more flexible. Most people use OBiTalk for simplicity.
http://www.obitalk.com/forum/index.php?topic=92.0 talks of the differences and the perils of trying to use both for modifying settings.
But the Device Admin Guide says the un-ticking “Enable” will do the same thing. But it does not.
It also appears to be necessary to remove all the Obi-numbers. Should it not be possible to selectively set which callers have access to the AA?
Please correct me if I got it wrong.
Note that the Admin Guide is written from the point of view of not using OBiTalk. Most things that can be done directly on the local OBi web page can be done on OBiTalk. You should be using the web page built in to the OBi *OR* OBiTalk to change things. That is because if you use OBiTalk after changing settings locally, OBiTalk may overwrite your changes.
If you are using OBiTalk, the Admin Guide guide can still be useful. However you will need to do some modification to the techniques shown in the Admin Guide. The screen shots in the Admin Guide are all from the local web page.
"Selectively"... as in having a single list of permitted users of AA? Yes, that is what the trusted callers list is about. Now if you want a different list for various conditions, such as which line the person called in on, then you would have to mess with the strings. I think this could be done by using Expert mode of OBiTalk to override some strings.
So state whether you will use OBiTalk or the local web page to make changes. Trying to answer a question not knowing that makes things much harder, and it may affect who would try to answer your questions.
