  4. Challenges for Offering Subscribers High Quality VoIP Conversations • Delay, Jitter and Packet Loss are inherent to IP Networks and are unavoidable • All degrade voice quality • Even small amounts of packet loss and jitter can significantly reduce quality … • … resulting in unsatisfied customers and increased customer support costs • GIPS VoiceEngine mitigates IP network artifacts particularly in challenging conditions

  5. GIPS technology mitigates jitter, packet loss and reduces delay Unmanaged Internet Jitter Packet loss Delay

  6. Even in challenging network conditions GIPS significantly improves quality

  7. VoiceEngine provides all the necessary voice processing functions Audio options Codec preferences Network Type Echo cancellation Noise Suppression Volume settings Conferencing VAD, AGC Push-to-talk From Keypad (DTMF) Alternative decoder (G.729* etc) External encryption Error Handling Statistics VQMon Call setup SRTP GIPS VoiceEngine G.711, iLBC Enhanced G.711, iPCM-wb, iSAC decoders VQE To speaker Mixer NetEQTM From net Acoustic Echo Control SRTP From microphone Noise Suppression G.711, iLBC Enhanced G.711, iPCM-wb, iSAC encoders VAD Mixer AGC FEC To net Tone Generation Alternative encoder (G.729* etc)

  8. Fixed jitter buffer GIPS NetEQ™ 140 Jitter Adaptive jitter buffer 120 100 Delay (ms) 80 60 40 20 Packet number 0 0 200 400 600 800 1000 1200 1400 1600 1800 2000 NetEQ adapts to rapidly changing network conditions ~ 30-80 ms savings, one way, compared to traditional jitter buffers

  9. Benefits of GIPS technology • Embedded software solution that reduces your customer support costs and provides unmatched quality to subscribers • Proven technology – 100s of millions of downloads to date • Complementary technology to Ubicom Stream Engine • Ubicom Stream Engine prepares the packets for the network • GIPS VoiceEngine overcomes degradation during transmission • VoiceEngine an be utilized anywhere in the network • Consistent quality irrespective of the end point • Softclient or mobile clients can increase your value to your customers
