Abstract
The present invention enables a traditional analog telephone to be used with VoIP applications. For example, the user could connect their standard 900 MHz telephone to this invention, establish a VoIP call and enjoy the freedom of movement their cordless telephone provides. The preferred embodiment of the present invention minimizes overhead to the host computer via a dual CODEC modem that incorporates a DSP capable of simultaneous communication with the two CODEC modules. This architecture facilitates a latency and communication overhead reduction as the analog voice signals effectively “stream” from the first CODEC to the second CODEC.
