Technical Summary The traditional telephone system allows phone numbers to be moved from one carrier to another. This is referred to as number portability. When a phone number is looked up in a number portability database, various information can be returned such as an identifier for the responsible carrier or a new number that this call should by routed to. This specification defines parameters for the the tel URI that allow the tel URI to carry the carrier identification, a routed number, and an indicator that indicates that the number portability lookup has already been done. Working Group Summary The working group has consensus on this document and reviewed it for a long time. No significant concerns were raised. Protocol Quality The specification was reviewed for NITs by Alexander Car and Vijay Gurbani.
