Successful VoIP planning
Six steps for successful VoIP planning
1. Network Inventory2. Network Configuration Analysis3. Network Utilization Analysis4. Modeling the Converged Communication5. Simulation Voice Readiness Assessment6. Review
Ask yourself the correct questions before the rollout.

1. Network Inventory• Data Network Inventory
– How many Switches, Routers?– How many links between what sides?– How much bandwidth should I have?
• Voice Network Inventory – How many phones, fax, modems?– How many Gateways to PSTN, lease lines?
• Unified Communication (Server) inventory – Do you have a Contact Centre?– Is there any integration with your Mail-Server?– Do you have other Servers or Databases involved
in a Unified Communication service

2. Network Configuration Analysis• Data Network Configuration
– Do you have a end to end QoS strategy?– Is the configuration entered everywhere– Is every port configured correctly?– What version of cabling do you have? (CAT4,5,6, Fibre)
• Voice Network Configuration
– How many phones/fax do you have per side?– What codec's are you using?– How are the trunks configured?– What Voice call profile do you have?

3. Network Utilization Analysis
• Data Network utilization analysis
– How big is the utilization of your routers?– How big is the utilization of your switches?– How big is the utilization of your Links?
• Voice Traffic utilization Analysis– Who is talking with whom how long? => Call Profile– Busy hour Call attempts– Where are the gateways?– Are there different level of users? (VIPs? )

4. Modeling the Communication• Data Network Bandwidth
– How bursty are your data applications?– What other Applications are using which Diffserv classes?– Where are the bottlenecks and where is bandwidth expensive ?– What is the target usage?
• Voice Network Bandwidth– What Codec's and Packet sampling rates do you want to have?– How big is the busy hour call volume?– What is the target usage?
• Be prepared the volume will grow – Check your data volume growth in the history and make an assumption– The communication may change due to VoIP?– (Video)

5. Simulation and 6. Review• Simulation
– Can you predict the performance of an complex IP Network under load?– Are you sure all devices are configured and perform as they should? – How many calls are you able to simulate in parallel?– How do you predict the R-Value in the busy hour?– How do you collect that distributed results?
• Review – How do you documentation your inventory results?– How do you document your utilization, modeling and simulation results– What do you justify if you need to invest in the data network?

Successful VoIP Implementations
1. Implement access to all network components2. Implement synthetic background traffic3. Implement automated trouble shooting with
Vivinet Diagnostics4. Implement data collection for Resource
Management and Capacity Planning5. Test your procedures in a VoIP Pilot project with
friendly users and customize your system
