1. A method comprising:
receiving, at a computer processor that executes a terminating call session control function, a first session initiation protocol invite message indicating initiation of a connection link with an end user device, wherein the first session initiation protocol invite message is received from a device associated with a user agent during an active call between the end user device and the device; routing, by the computing device and in response to receiving the first session initiation protocol invite message, the first session initiation protocol invite message to an advertisement server; receiving, by the terminating call session control function, a second session initiation protocol invite message from the advertisement server; directing, by the terminating call session control function, the second session initiation protocol invite message to a backend application server to instruct the backend application server to acquire a uniform resource indicator for the end user device; receiving, by the terminating call session control function and from the backend application server, an acknowledgement of the second session initiation protocol invite message; routing, by the terminating call session control function, the acknowledgement to the advertisement server to instruct the advertisement server to extract an offer of a value voucher from an application server, the value voucher being unique to an end user associated with the end user device; transmitting, by the terminating call session control function, the offer of the value voucher to the end user device; receiving, at the terminating call session control function, an indication that the end user device has accepted the value voucher; determining, by the terminating call session control function during the active call, that an account associated with the user does not exist; in response to determining that the account associated with the user does not exist, creating, by the terminating call session control function during the active call, the account associated with the user and a network-based storage locker; and instructing, by the terminating call session control function and in response to receiving the indication that the end user device has accepted the value voucher, a coupon server to store, during the active call, the value voucher in the network-based storage locker unique to the user and to inform the end user device that the value voucher has been stored. |
