Abstract
A method for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method involves the persistent storage of voice media on a communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network. Although latency may be introduced, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations. In addition, the capacity and robustness in not being affected by external interferences for both wired and wireless communications is improved.
