Abstract for group Telephone

We plan on using the included stereo codec (AK4565) for audio input
and output with a simple microphone (pre-amplified as necessary) and
speaker set up. We will digitize the raw audio data to the VoIP
standard format, G.729 mu- or a-law (depending on feasibility of
each), and then packetize the encoded audio per the standard for
transmission via Ethernet. Our internet phone will conform to the SIP
draft standard for only making calls and receiving calls. We do not
plan on implementing functionality such as conference calling, call
waiting, transferring, and the like. We will, given the permission of
the developers, build upon the Ethernet transmission capabilities
created by team JAYCam (Spring, 2004) such that we can also receive
incoming audio packets. We will also implement a function for entering
account information and dialing via the keyboard and serial
connection.
