Customer Situation and Challenges

• Customers are seeking to reduce communications costs, improve processes and productivity, and ensure business resiliency

• Benefits of IP communications applications are clear, but customers need cost-effective transition to IP Communications

Customers need low-risk, evolutionary solutions

Solutions must work with existing PBXs and voice mail systems

Most customers cannot afford change out everything at once

Integration with other tools and processes (directories, e-mail, mobile devices etc.) is also required


Customer Situation and Challenges

• Product lifecycles are forcing technology decisions

– Avaya Octel and Nortel Meridian Mail End-of-Life situation has caused customers to consider alternative solutions

– Large volume of equipment purchased prior to Y2K is reaching end of useful life

• Technology does not dictate your strategy

• Cisco® empowers you to intelligently plan your migration strategy


Fundamentals of the Migration

• Migration will take place over a period of time, it is not instantaneous

• Migration requires planning and coordination across the organization

• Migration should minimize short term and long term impact to users

• Migration choices are based on many factors, including ROI, long-term vision, organizational and geographic considerations, and “lessons learned” from past experience

BusinessAnalysis


Network Readiness

• Use QoS in LAN, MAN, and WAN

No shared media LANs—Switched LANs only

End-to-end QoS/Call Admission Control required

• Bandwidth requirements

Calculated total requirements, use Call Admission Control and cRTP

• Network availability

Network design, redundancy and best practices

• Network-based authentication and security

• Power for endpoint devices

Power budget in wiring closet, prepare for Power over Ethernet

• Plan for E911 support with automated location management

• Have a thorough migration plan


Deployment Planning

• Opportunities to migrate to IPC exist throughout an organization:

–Greenfield IP Telephony

–Large Site IP Telephony

–Remote Site IP Telephony

–Contact Center

–Voice Mail/Unified Communications

–Audio Conferencing

–Video Conferencing

–Mobile Telephony

• Where to begin is unique for each deployment, and depends on business and technology factors

Unity Migration


How Cisco Unity Eases Migration to IP Communications

• Cisco Unity® increases organizational effectiveness and employee productivity

Access to messages from anywhere, from any device

Enables employees to respond more quickly, increasing organizational effectiveness

• Cisco Unity interoperates with existing infrastructure—PBXs or legacy voicemail

Integration with existing TDM infrastructure enables customer to migrate at planned pace

Lowers operating costs—faster moves, adds, changes

Works with existing tools and processes (directories, e-mail, mobile devices, etc.)

• Customers can migrate to a full IP solution at their own paceCisco Unity can be installed prior to deployment of IP telephony and will work with IPT, protecting customer’s investment


Cisco Migration Example• Saving several million dollars annually

• Replace 160 Avaya systems with 45 Cisco Unity® systems

• Develop Best Practices that can be leveraged by our customers

Cisco Unity PBX IP Media Gateway (PIMG)

Legacy PBX

PIMG

•An 8 port, stackable integration device designed to offer a high quality connection between Cisco Unity or Cisco Unity Connection servers and your existing legacy Private Branch Exchange (PBX) switch •Emulates a digital phone (station) on the PBX side and connects to the Cisco Unity server on an IP connection using the Session Initiation Protocol (SIP)

•Up to 9 PIMG's can be stacked and connected to a single legacy PBX to provide up to 72 simultaneous voice sessions to the Cisco messaging server.
