4) Qos
QoS (Quality of Service) is a major issue in VoIP implementations. The issue is how
to guarantee that packet traffic for a voice or other media connection will not be
delayed or dropped due interference from other lower priority traffic. When the
network capacity is insufficient, QoS could provide priority to users by setting the
value.
Figure 4-15 Qos
Note: It's recommended that you configure the QoS in your router or switch instead of
TA FXS Gateway side.
5) Response Code
You can change the response code on TA FXS Gateway to the one you want before
sending it to the VoIP server. It helps the VoIP server understands better the exact call
status, like busy, no response and others.
