The reason voice quality is very poor is that IP traffic killed the voice traffic and
voice traffic cannot keep the constant bandwidth that is necessary to keep voice
quality, as shown in Figure 29.
Figure 29. BRS Super-Class Demonstration without BRS WAN Traffic
This time both 2212s are defined with BRS Super-Class and no IP traffic. Voice
quality using both side of 2212 FXS and E&M/PBX is very good. When WWW and
ping traffic is generated, voice quality will still be very good.
