The moment a company commits to migrate to VoIp technology, there is a need to analyze carefully the existing company processes and requirements, the projected short-term and long-term company needs, and the current bandwidth and speed of the broadband service the company have. These are primary not only to be able to comprehensively make a VoIp system tailor-made for the company but more importantly, to prevent possible failure of the VoIp system once in place.
VoIp Lifecycle Management
MOS
A methodology called VoIp Lifecycle administration (Vlm) thus emerged as a way to plan and manage the impact of VoIp deployment on existing Lans, and to manage and continuously pronounce the network after the company has transitioned to VoIp. The adding of new Ip phones, increasing data flow and the aging of tool might finally ensue in breakdowns, and Vlm works to anticipate these possible problems so that healthful remedies are implemented before the system fails. The Vlm has three definite stages: analysis, installation/testing and ongoing monitoring.
Analysis for Readiness
VoIp experts assessment that as much as 85 percent of existing company Lans are not ready for data and voice integration. Most of existing Lans grew organically, typically with the increasing of devices and cables here and there as the need arises, rather than from a ready network design.
Among the most foremost aspects that must be carefully contain the maximum concurrent calls (as the service provider needs to know beforehand how much bandwidth and facilities to reserve) and the calls per second rate (to prevent inundating the servers with hundreds of calls that may cause system crashes.
Installation and verification
Only after the existing Lan is verified to be capable of handling VoIp should one move on to the installation process. The system designer must make sure to:
Isolate VoIp traffic from data streams by building a Virtual Lan infrastructure Remove unnecessary hardware, routers, and switches from the points VoIp calls generate to the gateway exiting the Lan, as these hops increase latency Add rate-shaping and prioritization configurations to ensure that VoIp traffic takes precedence over other packets, especially at choke points like routers and firewalls
Once the VoIp system is in place, Vlm tools are available for testing the system and measuring the Mean belief Score (Mos) or the general capability of the phone call and sampling frequency software for detecting intermittent problems.
Ongoing monitoring
The work does not stop after the VoIp system is installed and tested. Ongoing monitoring and testing would be necessary, especially if older hardware and cables that are liable to fail are used. In fact, the testing must be done regularly, so that possible failures can be startling and disruptions in service are at least minimized, if not totally avoided, particularly for businesses that are fully network-dependent.
The necessity of undertaking these illustrate steps cannot be overstated. After all, industry experts say that the chances of failure if the readiness assessment is skipped in a VoIp deployment stand at 50 percent. And even the other half that may successfully deploy VoIp without pretesting faces a 60 percent possibility of monthly service disruptions.
