    Ask yourself the correct questions before the rollout.
  • 5. 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
  • 6. 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?
  • 7. 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? )
  • 8. 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)
  • 9. 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?
