摘要： Marking a keyframe of a media stream in a communication system involves one or more entry media switches in communication with one or more endpoints. An entry media switch receives a media stream from an endpoint, where the media stream comprises a sequence of packets with a keyframe. The keyframe is detected and marked with a keyframe indicator. The keyframe indicator is operable to notify a downstream device of the keyframe. An output media stream is outputted.

摘要： A system and method for consolidating media signaling to facilitate IP telephony includes receiving a first message exchange in a first protocol from a first endpoint to negotiate a media path with a second endpoint. It is determined to consolidate the first message exchange with additional message exchanges received from the first endpoint in the first protocol. A second message exchange is received in the first protocol from the first endpoint, and information derived from the first message exchange and the second message exchange is consolidated. A first message exchange in a second protocol is initiated to the second endpoint according to the information consolidated from the first and second message exchanges in the first protocol. One or more media flows is facilitated over the media path between the first and second endpoints according to the first and second message exchanges in the first protocol and the first message exchange in the second protocol.

摘要： A method of communicating information between a first program and a second program over a network is described. The method includes relaying the information between the first program and a first communications program over a first network connection, relaying the information between the first communications program and a second communications program over a second network connection and relaying the information between the second communications program and the second program over a third network connection. Further, the first communications program creates the second network connection to the second communications program through a first firewall program, which prevents access to the first program initiated by the second program. Thus, the second network connection is initiated by the first communications program. The first communications program can be, for example, a protocol daemon and the second communications program can be, for example, a relay program. The first firewall program can also be configured to prevent access to the first program initiated by the second communications program.
