Successful VoIP planning Six steps for successful VoIP planning 1.Network Inventory 2.Network Configuration Analysis 3.Network Utilization Analysis 4.Modeling the Converged Communication 5.Simulation Voice Readiness Assessment 6.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 components 2.Implement synthetic background traffic 3.Implement automated trouble shooting with Vivinet Diagnostics 4.Implement data collection for Resource Management and Capacity Planning 5.Test your procedures in a VoIP Pilot project with friendly users and customize your system

IP Network IP Network 1. Implement access to all components Control Centre Call Servers, Signaling Server IP phones, VoIP Gateways Voice mail systems IP contact center applications, The underlying IP infrastructure (routers, switches, FW)

2. Implement synthetic Background Traffic Performance Endpoints as part of standard PC-built. Performance endpoint on dedicated devices Permanent Real-time end to end VoIP Quality measurement and alerting => Very good data source for trending analysis. PSTN IP-Network Control Centre

3. Implement automated trouble shooting VD Triggered by synthetic background traffic (VoIP Quality Module) VD Triggered by Phone Polling Cisco, VD Triggered by Nortel QoS Alarms –From Phase 2 Phones and the 2050Softphones SNMP Trap: QoS0028 R-Value, QoS0021, QoS0023 –From Nortel VGMCs SNMP Trap QoS0021 SNMP Trap QoS0023 Control Centre
