2. 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, , mobile devices etc.) is also required
What are the challenges facing customers to move from today’s network to a fully converged IP network running IPC applications?

3. 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
What are the challenges facing customers to move from today’s network to a fully converged IP network running IPC applications?

4. 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

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

16. Unity Migration

17. 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 voic
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, , mobile devices, etc.)
Customers can migrate to a full IP solution at their own pace
Cisco Unity can be installed prior to deployment of IP telephony and will work with IPT, protecting customer’s investment
Cisco Unity is an easy first step to take to start deploying IP Communications applications
It works with your existing TDM infrastructure and with Cisco CallManager, enabling you to realize the benefits of an IPC application while you migrate
It also enhances your existing Exchange or Domino messaging applications, enabling better productivity without having to completely replace an existing application.
Some Unity customers (about 15%) install Unity ahead of Call Manager, and as Call Manager is deployed the migration is seamless

18. 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
In the US, within 5 weeks of the Unity deployment to users, the number of calls to the help desk dropped below the number of calls with the previous Octel system.
Centralized management of all of the Unity systems also decreases operating costs

19. Cisco Unity A Powerful Migration Tool

List of integrations continues to grow with ongoing testing/trials
New PBX’s are added to the supported integrations list on a regular basis
The new candidates for inclusion are based on customer demand
Cisco uses what is called the Out-of-box (OOB) process to qualify new integrations. (This is because we are not able to procure and test against all legacy PBX hardware)
For out of box process, account team submits request for PBX OOB consideration
Cisco Unity technical team reviews request for integration suitability
Customer runs test plan with help of SE/distributor
Once testing successfully completed, internal documents and processes updated/implemented to support new integration

All VPIM messages go through the Internet Voice Connector,
This is for both in bound and out bound traffic.
Incoming messages do a global search, so, there can be no dialing conflicts in the Unity Network

Cisco Unity supports the Voice Profile for Internet Messaging (VPIM) protocol, which is an industry standard that allows different voice messaging systems to exchange voice, fax, and text messages over the Internet or any TCP/IP network. VPIM is based on the Simple Mail Transfer Protocol ( SMTP) and the Multi-Purpose Internet Mail Extension ( MIME) protocol.
Here’s an example of message flow

Pros
In the past year, Cisco Unity has come a long way, adding to our analog AMIS solution for message interoperability with Cisco Unity Bridge. Cisco Unity Bridge provides more advanced messaging capabilities (such as hit “8” to reply in addition to basic subscriber-to-subscriber messaging) for message interoperability to Avaya/Octel voice mail systems using Octel Analog Networking. In addition, support of VPIM (Voice Profile for Internet Messaging) was added that provides for efficient, digital, message interoperability with systems that support VPIM.
It is important to note that ALL THREE of these options should be considered even though VPIM provides the best features and most efficient means of transport. Although AMIS is analog and only provides subscriber to subscriber messaging, it may be the right choice for your customer who has support for AMIS already with their traditional voic system they want to replace. They often would need to purchase a software upgrade from Nortel, for example, to get VPIM support. And, by the time they’ve done that, they would likely not want to invest to replace that voice mail system with Unity. So, be sure you select the right option for your particular customer’s needs.
Basic subscriber- to-subscriber messaging only, no directory sync
Limited to Octel/ Intuity Interchange, no digital networking for Aria/Serenade, limited NDR
Not yet widely adopted or supported
No Directory change synchronization
