Some Observations
![Page 10: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/10.jpg)
VoIP has gone Mainstream
![Page 11: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/11.jpg)
VoIP is enabling the Best of Breed
• In the past, one vendor controlled all the technology
o “You can have any color phone you want, as long as it’s black”
• Going forwardo Softswitches, IP-PBX, Messaging, IVR…o Standard protocols and hardware platformso VARs and Systems Integrator are choosing
the best hardware and software for their application
o Creating value and products that fit needs
![Page 12: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/12.jpg)
What is the difference?

Increasing Density
• Moore’s law will continue to increase density (more functionality for less money)
o CISCo DSP o Packet Processors
• Shifting the role of dedicated hardware
![Page 14: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/14.jpg)
Emergence of New Blade Form Factors
• ATCAo Advanced Telecom
Computing Architecture o 140 sq. incheso 200 W of power/blade
• AMCo ATCA Mezzanine Card
• PCIExpresso Desktop and Enterprise
![Page 15: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/15.jpg)
New Form Factors
• “Blade” Servers• IBM, Intel, Dell, Compaq, etc.• Very high computational density• Ideal platform for hosting applications • Proprietary, but “Open” form factor• Standard peripheral form factor
o Usually PCI
IBM BladeCenter

Death of the PCI Driver
PCIDriver
• Replaced by on-board protocols
![Page 17: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/17.jpg)
On-board Protocols
• On-board protocols are becoming the preferred control mechanism
• Using a standard or proprietary protocol to control a board or stand-alone deviceo SIP, VoiceXML, MSCML, MGCP
• Displacing the traditional API/Driver model
• No more PCI drivers!• Eliminates O/S dependence • Bonus: Better test tools (Ethereal)

Adoption of Blades vs. Boxes
• Software developers love distributed architecture using standard protocols
• Product Managers and Integrators have different challenges:o Cost Targetso Offering communications “solutions”o Branding issueso Fewer boxes
• Result:o PM & Integrators many times prefer
blades
![Page 21: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/21.jpg)
One Code Base
• Today, many application developers are supporting two separate code bases:o One for TDM implementationso Second for VoIP interfaces
• Challengeso Maintenanceo Testingo Surrounding Management Softwareo Expertise on Boards and APIs
![Page 22: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/22.jpg)
One Code Base
• Mass movement to supporting only VoIPo SIP, H.323, MGCP…
• Using gateways to connect into TDM applications
• Why?o Only maintaining one code baseo Saves engineering resourceso Focus on the application, not the plumbingo Eliminates management of TDM interfaceso No driverso No O/S dependencies
![Page 23: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/23.jpg)
Need for Transcoding
• Wireline and wireless carrier depend on different voice compression formatso Different needs and limitationso G.729a favorite with wireline carrierso AMR or EVRC for wireless
• How to interconnect?o Transcoding Resourceso High Densityo Low Latencyo Excellent voice quality
Transcoding
![Page 24: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/24.jpg)
Focus on Security
Cable systems are the early adopters(multi-drop nature of cable systems)
• Call control Encryptiono IPSec and BTNS
• Voice Path Encryptiono SRTP
• Management Interfaceso HTTPS
• Customers will demand that equipment vendors will support new security standards
![Page 25: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/25.jpg)
Focus on Security
• Session Border Controller• Protecting your network / IP-PBX
from intruderso Network Isolation / Protectiono Encryption / Privacyo Protect against Denial of Service
Attackso Stand-alone devices (for now)
• What’s next:o Built-in to IP-PBX at the
Enterprise

The Last Mile
Carriers are depending on the existing broadband facility to the Enterprise/Consumer
![Page 27: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/27.jpg)
Voice Quality
• Greater dependence on existing IP infrastructure (Cable, DSL, T1, Wireless)
• Requires that equipment that can operate in “suspect” network performance.
• Dependence on low bit rate coders by carriers is increasingo More through the same pipeo Less congestion = less lost packetso Better voice quality
• More on this in a separate session
![Page 28: Alan Percy Director of Business Development AudioCodes](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649e035503460f94aeefa7/html5/thumbnails/28.jpg)
What to worry about
• Taxationo With the shift to VoIP, taxation
model will have to change.o Governments will need revenueo We need to guide their decisions
• E911o The solution is understoodo Can carriers react quick enough?o What other similar “legacy”
issues await?o Is there a better way?
• Will wireline phones really matter?
