VoicePacketizer Voice over IP Streaming Protocol Stack  
TM  
AudioCodes' VoicePacketizer is a highly portable ANSI C language software  
application library implementing RTP/RTCP encapsulation per RFC  
1889/1890/2198/2833. It has been tested to be compatible with most of  
the popular communication processors and embedded operating systems.

available software stacks (e.g. H.323, SIP). The VoicePacketizer typically

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 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

Convenient Functions for Fast Start-up

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

Benefit from Extensive Experience  
AudioCodes is one of the world's leading providers of VoP DSP solutions since  
1996. During this period, the company successfully passed numerous  
interoperability tests while maintaining high levels of performance. AudioCodes'  
commitment to innovation yields consistently high-quality voice processing
