VoIP Solutions
� Voice Over Broadband (VoBB)� Voice traffic that is carried across a broadband access link. � Voice over broadband services may be originated from households and business sites (mainly SOHO).
� IP Voice Over VPN & IP/TDM Trunking� This uses a company’s IP VPN solution to deliver on-net voice traffic between sites.
� It is commonly provided as a fully managed service.� IP/TDM trunking connects a TDM/IP PBX platform to the enterprise data network and to the public voice network
� Customer Premise Equipment based IP/Hybrid PBX� PBX housed in the Customer Site� This can be deployed with a blend of IP and TDM endpoints (lines or trunk)� The service of the CPE based PBX is often a Managed Service delivered by System Integrator or Service Provider
� Network Based Dedicated Hosted IP PBX � This is a fully outsourced, managed IP PBX service. � The service provider hosts the customer’s IP PBX at its own central office or datacenter.
� Network Based Multitenant IP Centrex � IP Centrex is based on a call management server, or next-generation soft switch� This is housed in a Carrier’s Network Operations Center (NOC)� It delivers all the features of a PBX and supports many functions not available on traditional PBX systems� IP Centrex model is shared between a number of enterprises. � It is aimed at businesses that want all the PBX functionalities but without the associated capital, lease, or maintenance costs.
� A very large panel of solution and service offering

Hosted Business VoIP – key take-aways
Targeted market : SMBs
� Minimal start-up cost.� For 20% of SMB, this is the 1st impact of the economic downturn on their deployment plan
� No need to hire technology support staff� #2 VoIP adoption driver for SMB, (after business application, but before cost reduction)
� Affordable Mobility functionality including fixed mobile convergence
� Fixed expenditures budgeted over a contracted period of time
� Access to appropriate expertise as technology needs evolve
But still strong resistance :
� Comfort level with equipment on-premise
� Hosted IP is a change => Longer selling cycle (education, concept prove-in,…)
� Threat for IP PBX vendors. Tier1 SPs avoid competition with vendors
� 1st Target : Greenfield SMB / Start-ups � Strong growth through the next several years
17 | GP Informatique et Telecom – All-IP 11 Mars 2009
IP Voice Over VPN & IP/TDM Trunking – Key take-aways
� IP communications benefits without transitioning to Hosted (psychological step)
� Substitute for hosted for customers with existing premise equipment
� Introductory approach to small businesses
� Requires upfront CAPEX : upgrade of existing CPE
� Primary target : SMB with existing CPE �IP Trunking is an Avenue to Hosted IP Telephony
18 | GP Informatique et Telecom – All-IP 11 Mars 2009
Managed Services evolution – key take-aways

Drivers for move to All-IP
VoIP is rapidly becoming a mainstream choice for corporate customers,But… not just a question of cost saving on long distance and local service
� Cost saving benefits have become commoditized and are considered a given
� Integration with wide ranging business applications and convenience are the most important considerations
� To accelerate IP convergence value proposition of IP telephony has shifted :
Cost-centric benefits -> Applications-centric rewards.
� Business VoIP is as a catalyst for migration to an infrastructure and services that deliver a truly Unified Communications environment.
25 | GP Informatique et Telecom – All-IP 11 Mars 2009
Roadblock for move to All-IP
Economic Downturn reinforces some of the usual roadblocks:� The move to all IP has been heavily slowed-down
� IP lines will not outship legacy Analog and Digital lines until 2010
� Customers continue to focus on Reducing cost and Maintaining current capabilities
1. Reducing Cost� Smooth transition of IP lines (endpoints)
� LAN impact. Infrastructure upgrade required for Quality of Service (QoS) and Power over Ethernet (PoE).
� Write-off of Digital phones
� Dependency on FMC, Dual-Mode handsets availability and adoption
2. Maintaining current capabilities� Postponement of PBX replacement cycles
� Smooth migration to maximize re-use of install base
� Plenty of solutions developed by vendors & providers
� Allows to protect providers market share, but does not generate expected growth…
� UC required as a Revenue Growth vector

Unified Communication / Definition
� Unified Communication IS NOT a single product.
� Unified Communications IS :
� VoIP. VoIP-based call processing is a building block for UC, but VoIP aloneis not enough to provide UC.
� Email & Unified Messaging. While UM simplifies message access and is generally part of a UC strategy, it is not, by itself, UC.
� Instant Messaging. Instant messaging has now become a staple business application and a popular way to communicate.
� Presence. Users may be logged in to multiple devices. They make their status known to other co-workers and to specify which communication mode is preferred at given times.
� Video. Users can call colleagues and then decide to add video by clicking an icon.
� Web-Based Conferencing and Collaboration. Team members separated by geography need easy–to-use communications applications that enable collaboration.
�Communication towards a new user experience
29 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication benefits
� More direct collaboration between co-workers and with suppliers and clients, even if they are not physically on the same site
� Decrease the number of abandoned customer calls
� Increase responsiveness
� Save Cellular charges
� Streamline estate and user management
� Optimize fixed telephony infrastructure
� Reduce Human Latency with business process integration

30 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication Benefits / Illustration
� Corporate directories / Vacation Request use case� Transactions that normally take place in an SAP interface can instead be
executed in other applications with which end users are more comfortable.
� An end user could request a vacation by blocking out the time in his Outlook calendar.
� This action would trigger a leave request that would be routed through the company's systems using all the rules within the SAP application.
� Managers could approve or reject the request much as they would a meeting request in Outlook.
� Customer Relationship Management / Insurance use case � A call center agent at an insurance company might receive a call from
someone who wants to insure a diamond ring.
� The agent collects basic information about the potential customer and enters it into an SAP-based insurance underwriting application.
� Through a presenceclient integrated with the application, the call center agent will then be able to see a list of the company's insuranceunderwriters.
� Then through an immediate instant messaging session or a phone call, the agent goes over the basics of the prospect with the underwriter to determine whether the company will insure the ring.
� The customer get a real-time answer -- yes or no
31 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Challenges
� UC is an emerging area
� Salespeople don’t yet have a ‘winning formula’for driving signatures for UC solutions
� Diversity of factors making competitive selling difficult
� Not just the traditional competitors, but new competitors as well
� New competitive offerings emerging constantly
� New buying centers (Telecom + IT)
� Customer value metrics for UC are not fully understood, making it difficult to position the Unique Selling Propositions of a UC offer
� No compelling differentiation longer sales cycles, lost business

Unified Communication / Competition market
�But several IT and communications domains are fighting for control
34 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Telephonic centric Approach
� Strategy� IP PBX and UM are viewed as the starting point for UC
capabilities. � The functionality offered is telephony-centric, and not all the
functions associated with UC are available.� These solutions are extensions of IP-PBX and UM products. In
some cases, UM is tightly integrated with the PBX, the two are offered by separate vendors
� Partnership with desktop application vendors is mandatory
� Strengths� Voice expertise� Installed base
� Weaknesses� Ecosystem lacks application � Solution selling capability
� Maturity� These products, as offered by the leading telephony vendors,
are mature� They have been on the market since the late 1990s, so the best
practices around deployment and use are established.
35 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Messaging & Collaboration Approach
� Strategy
� With presence as the backbone, UC makes this set of communications capabilities available from within the business processes and applications that information workers use most.
� their software solutions are likely to be positioned to replace much of the call control functionality that currently resides inthe PBX hardware
� Strengths
� Own the desktop user interface (around 95%)
� Strong IT relationships
� Leader in collaboration and a footprint in business apps
� Ability to support heterogeneous IT environments and PBX
� Weaknesses
� Ecosystem lacks business telephony expertise
� “One size fits all” box-shifting orientation
� Maturity
� They are quite mature for small businesses but have not proved their scalability or reliability for large enterprises
36 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Service Providers Approach
� Strategy
� Mobility and Conferencing are viewed as the heart of UC.
� This approach integrates on-premises and service offerings, and has its roots in a range of network-based service solutions.
� Strengths
� Network is coordination point for UC
� PBX reseller relationships
� Global providers enable access points in all regions
� Weaknesses
� Lack IT relationships
� Some of the confidentiality, security, reliability and best practices are not well understood
� Maturity
� Although application service provider and hosted solutions have been available for several years, they have proved inadequate for addressing the full set of enterprise needs.
37 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Enterprise Application Approach
� Strategy
� Integration of communication into vertical and horizontal application (CEBP)
� Integration of social network
� Partnership/acquisition with infrastructure vendors
� Strengths
� Significant market presence
� Financially secure
� Middleware expertise
� Weaknesses
� Although some individual components are mature, the overall solution is in an early stage, is fragmented and has not yet matured as a consolidated UC solution
� Enterprise telephony and IM (SDP) are primarily hosted; however, premise solutions are available, although they are deployed less
� Maturity
� Not yet matured as a consolidated UC solution
38 | GP Informatique et Telecom – All-IP 11 Mars 2009
Unified Communication / Forecasts
� Quantifying the UC market is extremely difficult, as there are various ways of defining UC, and each definition brings with it a different way to measure the market.
� UC revenues are expected to rise from $11.7 B in 2008 to $15.0 B in 2013, yielding a 4.9% 5-year CAGR
� The components or elements included in this forecast are Enterprise Instant Messaging/Presence, IP PBXs, Unified Messaging, Conferencing/Collaboration, UC PBX Integration and other (including soft phone).
� The components showing the strongest growth during the forecast period are enterprise IM/Presence, and UC PBXDell ORO Jan09
39 | GP Informatique et Telecom – All-IP 11 Mars 2009
Conclusion
� Unified Communications is all the rage.
� The real ROI comes from when UC is tied to business processes but it is not essential to reach that phase to reap significant benefits from UC.
� While there are clearly many benefits to UC, there are also significant challenges that must be overcome in order for the market to reach its potential.
� No one single vendor provides all of the UC elements for a complete UC solution so each vendor should re-evaluate its role and forge alliances
� The first vendor that will successfully design, sell, and deploy UC solutions, will be in a position to lock in value-added customer revenue for years and years to come

All-IP Migration Vs IP Overlay
All-IP Migration
The all-IP migration approach mandates a flash-cut approach consistent with a total network replacement model.
Nevertheless, even in a single next-generation network configuration, with no legacy switching cited as aligned with the all-IP option, it does not involve a single flash-cut, but rather consists of an orderly timeline of TDM replacement.
Beware of the cost in testing the multitude of possible combinations in migrating the traditional services such as Frame and ATM to Ethernet and IP with or without inter-working functions in between.
The issue is not "if" wireless operators will move to an all-IP Radio Access Network (RAN), but when?
47 | GP Informatique et Telecom – All-IP 11 Mars 2009
All-IP Migration Vs IP Overlay (2)
IP Overlay
• In the IP-overlay scenario, the network operator simply deploys an IP network in addition to its TDM infrastructure.
• Legacy services are supported via a silo model. TDM customers are not able to gain access to new multimedia services.
The issue is not "if" wireless operators will move to an all-IP Radio Access Network (RAN), but when?
48 | GP Informatique et Telecom – All-IP 11 Mars 2009
NGN Vs IMS
• 6 layers:
• Application: added value services
• Call Processing: call management
• Transport: ATM or IP based
• Adaptation and connection through media gateway
• Access: Link between end users and the network.
• Terminals
49 | GP Informatique et Telecom – All-IP 11 Mars 2009
NGN Vs IMS
Many operators that initially deploy NGN soft-switch-based solutions continue to view transition to IMS as a mandatory step. Furthermore, closely aligned in standards, evolving from soft-switch to era of IMS is well defined but does introduced a second cutover phase.
• 5 layers:
• Application: added value services
• Call Processing: call management and session control on the PS domain
• Transport: IP based
• Access: Link between end users and the network.
• Terminals: SIP enablers.
50 | GP Informatique et Telecom – All-IP 11 Mars 2009
Impact of All-IP in the access
• IP Access Transport Network
• Cost reduction by reducing E1/T1 leasing.
• Additional bandwidth
• Voice and data on a common facility
• Impacts of Femto Cells
• Introduced in 2005 3GPP, concept of a small based intelligent wireless radio access node.
• Provide mobile carriers with the technology to compete with fixed network operators.
• SIP-enabled, extremely well suited to integration within IMS architectures
• UMTS Beyond rel-8, LTE and Wimax
• Delivery of broadband to the wireless end-user, equivalent to fixed network broadband capabilities.
• Provide mobile carriers with the technology to compete with fixed network operators.

• New service revenue not known
• Control and plan site transition => cost are driven
• Faster decommissioning of legacy network.
Carrier driven
(Based on provider schedule)
• Rapid adoption could cause extreme workload=> higher opex
• Lack of control of site conversion
• Lower initial capex
• Greater customer tolerance for transition issues
Subscriber driven
(End users opt for IP-Based services)

Beyond IP transformation
Wireline and Wireless operator convergence
• Disruptive technologies allow identical services (e.g. VoIP) used by wireless operators and fixed operators.
• Leveraging of the IP backhaul
• Leveraging of services and applications in both access
• Probably for full benefit of the end-user by enabling the mix of both mobile and landline services.
