UBIFone

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.

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 Why The Current Technology Is Not Good Enough?

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 VQE

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

GIPS NetEQ TM 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

GIPS Codecs Narrowband codecs –GIPS Enhanced G.711 TM –iLBC TM Wideband codecs –GIPS iPCM-wb TM –GIPS iSAC TM

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 Best possible PSTN Quality* Best possible Cell Phone Quality* Hang-up, intolerable speech degradation

MOS: GIPS Codecs

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

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!
