When an application server receives an invite message associated with a call from an originating user equipment (UE) to a terminating UE, the application server can determine if one of the originating UE or the terminating UE is associated with a scammer. If the originating UE is associated with a scammer, the application server can remove the scammer's caller identification (ID) information from the invite message, such that a user of the terminating UE cannot use that caller ID information to make a return call to the scammer. If the terminating UE is associated with a scammer, the application server can remove caller ID information associated with the originating UE from the invite message to hide the calling party's information from the scammer, and/or invoke playback of a scam announcement to the originating UE to warn the calling party that they are calling a scammer.
