Asset Inventory: know what you by providing a complete inventory of all network hardware to work, including switches, routers, servers, existing PBX, cabling and end user devices. Make sure to take their computing performance and throughput, and all nodes that are not aware of VoIP. Also be sure to router OS versions and document WAN connections to the Internet.

It may be that certain equipment must be refurbished or upgraded in retirement. For material inappropriate for a segment to other areas of your business where you can reuse your existing hardware, perhaps a branch of working age who are not used in a demand compared the near future.

Also take a good look at all your business applications, their versions and any necessary patches or upgrades which should be implemented. It is now time to decide what applications you can do without and to create order, and bring in all new and improved versions of the applications critical to your business needs. Get together with all available patches for applications and operating systems, and electricity.

Take the opportunity at this time your current telephony environment, such as call center configurations, slowly working normally, and evaluate a call with the call patterns, connection time, inter / intra office models. All the information you collect on your calling environment will be used to set standards and identify ALS in the new converged environment. Inventory of all current voice equipment to determine their usefulness and depreciation schedules. During the mission, you will more than likely that an old PBX or keep as a backup to two.

Network Assessment: One of the most important steps in planning the voice is the Network Readiness Assessment. Most VoIP providers is to determine a network assessment for you which parts of an existing network that requires an upgrade to produce an acceptable level of call quality.

For companies that manage their own operations in progress, network assessment tools are available, and this should be part of your global solution network analysis software. The evaluation of the first network in the planning phase is to determine if you need to upgrade, should subsequent assessments periodically on a monthly or quarterly are performed to see how changes in the network have an impact on performance.

Assessment tools are hardware or software-based, with software the method preferred that the entire network can be evaluated from a central location. A software tool sends agents into the LAN and WAN links to remote locations, simulating voice traffic to determine how many VoIP calls can be treated on the basis of indicators of service quality and MOS from one location.

The first assessment of the readiness of VoIP should be made through an entire cycle. Simulate peak calls to various places and evaluate other business applications that reside on the network, how to handle the additional voice traffic and its impact on the quality of the connection and respond QoS.

It was established in the industry that 50% of the full IPT deployments that do not make an assessment of the network by the end deployments failed, many of them money to upgrade their networks, they have thought they needed, rather than where they knew they needed it.

For some smaller companies, the convergence could be as simple and inexpensive as installing an Asterix PBX on a dedicated computer or a peer-to-peer like Skype to communicate between branches. For companies that will maintain its own infrastructure, lack of planning, testing and evaluation for IPT certainly lead to a mission fraught with dropped calls, poor call quality and connection time and possible disruption of your business to other business-critical applications.
