Abstract

Aspects of the invention relate to systems and methods of providing voice communications over a packet switched network having one or more client device connected on a low bandwidth connection. One aspect allows VOIP connections to adapt to the various, and potentially changing conditions, caused by different connection types and transmission qualities. One aspect modifies the data, the encryption methods, the sampling frequencies, and other parameters of the VOIP configuration to improve the functioning of the VOIP communication. These parameters may be changed based on the connection types and transmission quality of both the sending and receiving devices, among other factors. Another aspect of the present invention relates to methods of predictive voice transmission by constantly recording into a buffer and only transmitting portions of the buffered recording based on the presence of voice.
