Abstract:
Systems and methods for identifying and blocking undesired automated calls include checking to determine if more than a predetermined number of calls are received from the same originating telephone number within a certain period of time. If so, information about the calls from the same originating telephone number is analyzed to determine if the calls conform to one or more patterns that indicate the calls are likely undesired automated calls. If so, further calls from the originating telephone number may be blocked.
Abstract:
When an IP telephony system is attempting to setup a telephony communication between a calling party and a called party, the system monitors to determine if any audio or video is played to the calling party as early media. If so, the detected early media may be analyzed to determine one or more characteristics of the early media. The analysis may determine if early media is designed to cause the calling party to prematurely terminate the call setup attempt.
Abstract:
Systems and methods performed by a telephony device allow the telephony device to test the quality of multiple potential paths which can be used to conduct a telephony communication. By testing the conditions that presently exist, the telephony device can choose the path that is presently offering the best quality. A telephony communication may be setup over an initial path, and then subsequent testing may determine that it is best to switch to an alternate path offering better call quality. The initial path used for the telephony communication may be the one that offers the fastest initial connection. When multiple potential paths exist, the telephony communication may be conducted over a first path while keep alive messages are communicated over a second path so that the telephony communication can be quickly switched to the second path.
