Embedded VOIP SIP Developers Kit 1.2

Embedded Windows CE VOIP Developers Kit is your embedded telephony solution for developing software/hardware to enable device to device phone calls using SIP/H323 phone right at the electronics level.

The design is based on Hybrid Combination of RFC SIP Protocol and Windows RTC and is today successfully ported to Windows CE/Pocket PC/Smart Phone. With a memory overhead of 3 MB - the telephony engine very well fits the needs of engineers looking for porting highly advanced SIP or H323 PROTOCOL to the embedded world. Research Lab further enables you to create production level voip system with following tools

Available : A complete multi-lingual speech synthesis workbench using Festival TTS

Available: A complete multi-lingual speech recognition workbench using ISIP ASR

Available: Speaker Verification (with two algorithms)
Ported to Embedded : Edinburgh Speech Tools Library
Ported Open DSP Library : libsnd.dll
