Abstract: A method includes receiving, at a call block system, an indication of a call to a communication device. The method includes, in response to the indication and based on a determination that a call block feature is disabled for the communication device, outputting a first tone from the call block system to the communication device. The method further includes, in response to the indication and based on a determination that the call block feature is enabled, outputting a second tone from the call block system to the communication device.

Abstract: A computer implemented method includes outputting a dial tone from a call block system. The dial tone indicates to a calling party that a call block feature is enabled for a party. The computer implemented method includes storing messages for the party when the call block feature is enabled.

Abstract: A dial tone generator outputs a particular dial tone to a party to indicate that a call block feature is enabled for the party. The call block feature is disabled for the party in response to a number of incoming calls for the party being greater than or equal to a threshold.

Abstract: A first data packet is sent through a system under measurement (SUM) from a sender side to a receiver side. A time distance d between the first data packet and a second data packet consecutive thereto in a packet flow is observed on the sender side. A value of d is written into a payload of the second data packet. The second data packet is sent through the SUM. The first data packet and the second data packet are received on the receiver side. A time difference D between the first data packet and the second data packet is observed on the receiver side. The value of d is extracted, at the receiver side, from the payload of the second data packet. The jitter is determined based on the value of d extracted from the payload of the second data packet and the value of the time difference D.

Abstract: A method of improving the reliability of peer-to-peer network downloads includes the steps of initiating a search from a client on a peer-to-peer network. Next, a list of servers is downloaded that satisfies the search. At least one of the servers is selected from the list of servers. Next, one of a plurality of downloading systems is selected based on a predetermined criteria. A file is downloaded using one of the plurality of downloading systems.

Abstract: A method of improving the reliability of peer-to-peer network downloads includes the steps of initiating a search from a client on a peer-to-peer network (152). Next, a list of servers is downloaded that satisfies the search (154). At least one of the servers is selected from the list of servers (156). Next, one of a plurality of downloading systems is selected based on a predetermined criteria (158). A file is downloaded using one of the plurality of downloading systems.
