Abstract: A user device displays advertisements that invite potential customers to respond. Responses to the advertisement (i.e. sales leads) are sent by the user device to a router. The router identifies the responding user device and compares the user device with a security blacklist. The router also compares the user response with an advertising campaign list and queues appropriate responses for routing to a salesperson client. When an salesperson client becomes available, the router routes the queued response to the salesperson client. The salesperson client establishes a communication channel through the router with the user device. This enables an interactive marketing session between the salesperson client and the user allowing a bot or salesperson to further develop the sales lead.
