ABSTRACT:
A method and system for facilitating collection of past due balances. A control entity such as a call server or collections server receives a signaling message such as a SIP INVITE that seeks to set up a call between a calling party and called party. The control entity determines that the calling party has a past due balance, i.e., that the calling party owes the carrier money. In response, the control entity changes the signaling message to designate a collections system as the called party, and the signaling message is then used to set up a call between the calling party and the collections system.
