Avaya offers customers a tiered approach to deal with network packet loss to balance new network costs and the constraints of business directives.

The maximum loss of IP packets or frames between endpoints must be:

• 1% or less for best quality.

• 3% or less for Business Communications quality. Business Communications quality is much better than cell phone quality.

• 3% and above is acceptable for voice but can negatively impact signaling, which can degrade voice quality due to increased traffic. For more information on signaling bandwidth requirements, see the white papers on the Avaya Support Web site at https://support.avaya.com.

Thìrd-party tools, such as Prognosis, can measure packet loss for ongoing calls.
