The following example describes an automatic VoIP peer

change when ASR2 values result in a connection that no long-

er corresponds with the quality standards. Traffic with an

ASR2 value of over 30% for the last 30 calls is sent to IP ad-

dress 172.16.0.80. When the ASR2 falls below 30%, profile 

iG2

is used. After one hour has passed, the connection quality at

the original peer is automatically tested. If the connection cor-
