A method comprising directing a user equipped with a user's phone to a landing page in response to a call request to a call server communicatively coupled with a dynamic number insertion service (“DNIS”) provisioning server is disclosed. The user may be presented with an offer visible on the landing page such that the offer may be associable with the user's IP address. A user record may be created such that the user may be identifiable through a plurality of unique identifiers. A dynamic DNIS may be provisioned using the DNIS provisioning server such that a called ID associable with the landing page may be generated and the dynamic DNIS may be dialed such that the called ID may be captured. The user record may be matched using the dynamic DNIS and the dynamic DNIS may be released for re-use.
