发明名称 Marking and screening telephone calls
摘要 A system and method that controls calls, such as telephone solicitations, by a calling party to a called party. A switch receives a call from the calling party and marks the call to identify it as a telephone solicitation. Such marking can be performed in various ways, such as altering a forward call indicator of an IAM message if the switch is using an ISUP procedure, or providing a station type with information digits used in multi-frequency signaling. After the call has been marked, it can then be identified by a switch serving the called party as a telephone solicitation. Once identified, the switch then analyzes a profile for the called party and determines how to complete the call. For example, if the profile indicates that the called party does not want to receive telephone solicitations, the call will not be completed to the called party, but instead will receive alternate treatment.
