The present invention provides a method and apparatus for creating a
packet using a digital signal processor. Call set-up information is
received. Thereafter, call data is received and a data portion of the
packet is created using the call data. One or more headers are created
using the call data and the call set-up information. The packet is then
created by attaching the one or more headers to the data portion of the
packet. In addition, the one or more headers may include a real time
transport protocol header, a user datagram protocol header, an Internet
protocol header, and a media access control header.
