There's one thing that's been bothering me since I set up an OBi110 today. By default, the Line Port DigitMap was set to this:
(xxxxxxxS4|1xxxxxxxxxx|xx.)
I understand the first two rules - the first allows any seven digit number after a four second delay, and the second allows 11 digit calls in the US and Canada with no delay. But then there is the third one, which would seem to pass ANY number of three digits or more with no delay. Am I wrong in thinking the the third rule makes the first two superfluous?
I replaced that rule with:
(911|[2-9]xxxxxx|1xxxxxxxxxx)
Which I believe allows calls to 911, seven digit numbers NOT starting with 1, and eleven digit numbers starting with 1 to all go out with no delay. It would seem to me that such a rule would make more sense in the US and Canada. Some people might also want to be able to call other three digit N11 codes, and also two digit "star" codes to use custom calling features offered by the local telephone company, and in that case I am guessing that rules would have to be added to allow those, for example:
([2-9]11|[2-9]xxxxxx|1xxxxxxxxxx|*xx)
Is there anything wrong with my thinking here?
I suppose that Obihai doesn't know where their product will be used in the world when they sell it, but since I used the OBi Dashboard to configure the device, I was a bit surprised that they didn't seem to have anything that specifically configured the Line port in the "Configure Voice Services" section of the Device Configuration page. You can configure Service Providers 1 and 2 from there, bit if you want to configure anything on the Line port it seems you have to go into the OBi Expert Configuration Menu. I'm not at all uncomfortable doing that, but perhaps some new users would be. If they offered a Line Port configuration section, it could ask what country the user would be using the device in, and then adjust settings such as the Line Port DigitMap and certain other settings on the Line Port configuration page to the best default settings for that region. Just a suggestion.
