Systems and methods are described for processing calls. A call is received at a softswitch or other call processing system from a caller intended for a first subscriber. The first call is associated with signaling information, the signaling information including a phone number associated with the caller. A determination is made as to whether the first subscriber has previously received a call associated with the caller phone number at the softswitch. If the first subscriber has not previously received a call associated with the caller phone number at the softswitch, a first message is played to the caller. An indication that the first message was played to the caller is stored in association with an account record associated with the first subscriber.
