We currently offer custom dial plans for the US, Canada, Puerto Rico, Argentina, Mexico and Uruguay. Dial plans are assigned by choosing the country and region of a location, so for example:
If an administrator specifies that a location is based in the US, all users of that location will be assigned a US dialing plan.
Users from other countries can dial in E.164 format to any destination, e.g.: +1 (985) 655 2500. We plan on implementing more custom dial plans soon.
