Systems and methods to provide telephonic connections. In one embodiment, a method includes: providing a listing on a marketplace, the listing including an assigned reference to be used to initiate a real time communication connection; and billing for a real time communication lead generated from presenting the listing in response to a real time communication initiated via the reference. In one embodiment, a method includes: conducting online auction of telephonic leads; determining a way to present listings based at least partially on received price bids on the telephonic leads (e.g., the order of placement, the selection for placement, etc); and providing the listings with information to initiate a telephonic connection in a way trackable to measure a number of telephonic calls generated from presenting the listings.
