By default, the system will route media steams from SIP endpoints
through itself. Enabling this option causes the system to attempt to
negotiate the endpoints to route packets to each other directly,
bypassing the system. It is not always possible for the system to
negotiate endpoint-to-endpoint media routing.

410/810, a codec is a compression or
decompression algorithm that used in the transmission of voice packets over a
network or the Internet. For more information about codec, you can refer to this page:

If you want to use codec G729, we recommend buying a license key and input it here.
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 4-10 Qos
Note: It’s recommended that you configure the QoS in your router or switch instead of
TA410/810 side.
