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

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
