Outgoing Call restrictions using Google Voice

[gazarate]

Hello,

So far I have not been able to find the answer so I decided to post what I would like to do.

I have the obi110 and obi200 , basically I want to restrict outgoing calls to just a handful of numbers ,

Have someone be able to do this ?

Any help is really appreciated.

Thanks

Have a read of http://www.obihai.com/docs/OBi-DigitMapCallRoute-Tutorial-v1-1.pdf to get an understanding of DigitMaps.

Just change the Primary Line's DigitMap. I assume this is SP1.

Service Providers -> ITSP Profile A General -> DigitMap:
(1?8005551212|1?8005551313|1?8005551414)

Each number is separated by a vertical bar
The 1? will allow 10 or 11 digit numbers
Make this change using OBi Expert

With this change you will still be able to dial 911, speed dial numbers and some other special numbers.
See the following DigitMap for what is allowed:
Physical Interfaces -> Phone1 Port -> DigitMap
