A system for routing calls between a third party telecommunications device (“TD”) and a subscriber TD associated with a primary service and a second line service (“SLS”), the system comprising:

• an SLS platform that is in communication with a network of a primary service provider to the subscriber TD and a network of a primary service provider to the third party TD and configured to:
• receive a call routed to the SLS platform;
• determine that the call was routed to the SLS platform from the third party TD because it was directed to an SLS number associated with a subscriber to the SLS;
• identify a relationship number associated with both the SLS number and an actual calling number associated with the third party TD;
• and
• based on the relationship number, redirect the call to a primary number associated with the subscriber TD.
