OS
1889/1890/2198/2833. It has been tested to be compatible with most of
the popular communication processors and embedded operating systems.
The VoicePacketizer
TM
is compliant and easy to integrate with the widely
available software stacks (e.g. H.323, SIP). The VoicePacketizer
TM
typically
runs on the master communication processor of a VoIP gateway, access
multiplexer, or other packet network access or switching equipment.

Easy Integration to Gateway Application
A VoIP gateway application consists of two main components: a call setup
and signaling module and a stream processing module. The two are linked
by the application layer. The VoicePacketizer
TM
provides all stream processing
functions while the call setup and signaling modules can be purchased from
third party. The standard RTP/RTCP is extended to support a variety of voice
coders: G.711. G.726, G.727, G.723.1, G.729A/B and the NetCoder as well
as G3 fax relay (based on T.38) and DTMF relay (RFC 2833). The
VoicePacketizer

provides also the API for all DSP functionalities: Download,

Convenient Functions are a small set of functions, providing users with
simplified API containing larger building blocks to enable quick application
construction. Using the Convenient Functions, users do not need to directly
use the Initialization and Setup functions, AC48xx driver functions and most
of the Media Streaming Functions. These functions may also serve as a
reference code in case users want to use the basic VoicePacketizer
TM
stack聮s
function set. An application demo program is provided to show how to use
the Convenient Functions.
