[VoiceOps] 10 digit craziness

We've encounters this problem a few times both when dealing with carriers
and internally. When you start to mix VoIP and Traditional Telecom Carriers
it can get hairy with all the different formats they want calls in,
especially when you start dealing with international carriers.

We ended up standardizing our internal voice network on a CC+CityCode format
for all calls and then building specific translations for each carrier on
their inbound and outbound trunks.
