Adding VoIP taxes network resources and performance because VoIP requires dedicated bandwidth and is more sensitive to network problems than data applications alone. Many customer IP infrastructures that appear to be stable and perform at acceptable levels might have performance and stability issues that create problems for Avaya VoIP Solutions. Therefore, Avaya cannot assure performance and quality without a network assessment even when a customer network seems ready to support full-duplex VoIP applications.

In Avaya, the network assessment services for VoIP consist of two phases:

• Basic Network Assessment: A high-level LAN and WAN infrastructure evaluation that determines the suitability of an existing network for VoIP.

• Detailed Network Assessment: A detailed analysis of the information gathered in the basic network assessment to provide functional requirements for the network to implement Avaya VoIP
