1. A method for routing calls between a first party telecommunications device (“TD”) and a second party TD, the method comprising the steps of: provisioning the first party TD from a second line service (“SLS”) platform by: identifying the second line service (“SLS”) number to be associated with the first party TD, wherein the SLS number is a network addressable telephone number; establishing a data communication channel between the SLS platform and the first party TD; optionally transmitting over the data communication channel one or more relationship numbers to the first party TD, wherein each relationship number is associated with an SLS number of the first party TD and a network addressable phone number for the second party TD; receiving a call at the SLS platform, wherein the SLS platform is in communication with a network of a primary service provider to the first party TD and a network of a primary service provider to the second party TD and wherein the primary service providers provide primary service numbers to the first and second party TDs, respectively; determining that the call was routed to the SLS platform from the second party TD because it was the result of dialing an SLS number associated with the first party TD; establishing an additional relationship number that is associated with an actual network addressable telephone number for the second party TD when a call from the first party TD SLS number is initiated using the additional relationship number; transmitting over the data communication channel the additional relationship number to the first party TD; based on the additional relationship number, redirecting the call from the SLS platform to the primary number associated with the first party TD, wherein the leg of the redirected call between the second party TD and the first party TD is conducted via a voice channel; receiving a call at the SLS platform originating from the first party TD; determining that the call was routed to the SLS platform from the first party TD because it was directed to a called relationship number recognized by the network of the primary service provider to the first party TD; identifying the SLS number of the first party TD and an actual network addressable phone number for a third party TD all associated with the called relationship number; and redirecting the call from the SLS platform to the actual network addressable phone number for the third party TD, wherein the call between the first party TD and the third party TD is conducted via a voice channel.
