Is there a way to do this. We have a google phone at a vacation rental property and dont want anyone to call outside of the USA.
Cant seem to find a way to do this.
You don't have to worry about this if you didn't add money to your Google account. The call will fail.
You need to use OBi Expert to block international calls by doing this:
Service Providers -> ITSP Profile A General -> DigitMap:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx)
The above assumes GV is defined on SP1.
It will not block calls to the islands and I think there is a charge to call Hawaii and Alaska.
Do the following to block calls by area code. Replace ac1-3 with area codes you want to block. There are 2 entries for each area code, one with country code and another without. Add as many area codes as needed, each separated by a vertical bar.
(!(ac1|1ac1|ac2|1ac2|ac3|1ac3)xxxxxxx|1xxxxxxxxxx|<1>[2-9]xxxxxxxxx)
Here's a list of area codes:
