Avaya VoIP Deployment Considerations
Before you can deploy a certified VoIP solution, you need a network assessment to verify you have properly prepared your network for the VoIP traffic that will be running on it. Unless you have a great deal of experience in deploying VoIP, an assessment is suggested and if your plan is that "with this much bandwidth, we don't need QoS", then you ABSOLUTELY need an assessment.So, my first section is ....
The Network Assessment:
Performing a data network assessment is very different than performing a VoIP network assessment. Although the purpose of both VoIP and Data only networks is to move bits from host A to host B a very real difference exists in the requirements of each type of network. The function of VoIP technologies requires very strict standards that don't necessarily exist in a Data only network. Those standards, if not adhered to, will noticeably affect call quality.
Only in the last several years has the IT community generally accepted that VoIP Technologies are ready for the office environment and since its acceptance, have companies just begun to welcome VoIP technology. The slow acceptance of this emerging technology is despite the fact that same compression algorithms and standards for VoIP have been around for years. By far the largest reason that VoIP technology was not "ready for the real world" lies in the network that carried VoIP traffic not being ready. Even still today, if the requirements outlined in this and documents similar to this network assessment are not strictly adhered to, many companies find that they are not satisfied with the performance of their VoIP implementation.
