5. What is Compression Technology or CODEC? - CODEC is an abbreviation for Coder/Decoder • Highly popular with all storage related technologies • MP3 • DivX • AVI etc. - For VoIP the CODECs are G.711, G.723, G.729, GSM etc. - Core engine behind your SoftFones, IP Phones, Adaptors & Devices - Helps convert each voice signal to digital packets for transportation, and then reverses process so that it is humanly audible.

6. Why The Current Technology Is Not Good Enough? VoIP Technology Challenges LAN/Campus • Ethernet • Low delay and jitter • Low packet loss levels • Short periods of network congestion • Larger campus networks can experience significant jitter and packet loss • WLAN (and Hotspots) • Long delay and significant jitter (up to 500 ms) • Packet loss up to 40% during congestion • Poor coverage results in poor link quality Remote Office • Frame Relay/ATM • Subscribed rate that guarantees certain behavior • Unpredicted behavior with extensive jitter and packet loss when rate is exceeded • Expensive and non-flexible solution • IP VPN • ”Busy hours” characterized by delay, jitter and packet loss • Probed traffic shows packet loss levels up to 30% • Inexpensive, flexible and scalable

7. VQE VoIP Technology Challenges • Traditional packet loss concealment solutions introduce annoying artifacts • Traditional Jitter buffer design creates trade-off between long delay and voice quality • Standard codecs not designed for VoIP networks • Soft clients suffer from Windows related artifacts • Traditional echo cancellation not efficient enough

8. Birth of GIPS solutions • World renowned engineering team patented solution • iSAC CODEC • For PC to PC calls • 10 – 32 Kbp/s • High compression ratio, possible to deliver on all bands • iLBC CODEC • For PC to Phone calls • 13.3 – 15.2 Kbp/s • Open Source license, always improvising • iPCM-WB Codec • For PC to PC calls • 80 Kbp/s • Auto implements with high bandwidth availability

9. GIPS NetEQTM • Product Description • Advanced jitter buffer combined with superior error concealment • Benefits • Quick and high resolution adaptive jitter buffer • Highest rate of dynamic buffer size reduction resulting in shorter latency and higher voice quality • Deployed at receiving end only • Not dependent on system-wide deployment • NetEQ equipped end point receives quality benefits • Flag ship product adopted by all GIPS customers • Generic – works with any codec • Optimized support for GIPS codecs, G.729, G.729AB, G.723.1, G.711, GSM, AMR, G.722.x and many more • Interoperable with all codecs

10. GIPS Codecs • Narrowband codecs • GIPS Enhanced G.711TM • iLBCTM • Wideband codecs • GIPS iPCM-wbTM • GIPS iSACTM

11. Best possible PSTN Quality* Best possible Cell Phone Quality* Hang-up, intolerable speech degradation MOS: Subjective Listening Testing • Conducted by world’s leading testing lab, Lockheed Martin Global Telecommunications • Previously known as Voice Codec Evaluation Department of COMSAT Labs • 36 naive listeners subjected to 8-second sentence pairs • Read by both male and female speakers • Presented at random • Each sentence graded by listeners • 5 = excellent • 1 = bad • Reported score represents the mean of all votes *Best quality means clean, or perfect conditions

12. MOS: GIPS Codecs

13. Enhancement Components • Echo Cancellation & Suppression • Full duplex AEC with support for wideband speech • Lower complexity AES for PDAs • NEC included in VQE for ATA • Noise Cancellation & Suppression • Automatically suppresses or eliminates background noise from various sources, without suppressing voice volume or distorting voice quality • Voice Activity Detection & Comfort Noise Generation • VAD classifies speech frames as active or inactive while the user configurable CNG generates a comfort noise signal • Automatic Gain Control • Automatically adjusts speech volume to a comfortable level • Available in analog and digital modes to improve the SNR of the signal and prevent audio clipping

14. GIPS and UBIFone :: In a NutShell • Addresses all voice quality issues • Handles echo, background noise, and speech detection in one module, eliminating the need to buy multiple individual components • Optimized for better performance • All of the components designed together and highly optimized, resulting in a superior call quality and low complexity • Available on any platform • A field proven, real time solution for chip, equipment, and application providers, as well as low complexity devices such as PDAs • Immediate Results means more satisfied UBI Calls • Each new SoftFone downloaded, each new UBIFone call made, is more chances of proven quality, more chances of satisfied customers, more sales for your business!
