Allow RTP
Reinvite
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
3) Codecs
We can choose the allowed codec in NeoGate TA,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:
http://en.wikipedia.org/wiki/List_of_codecs
Figure III-4-13 Codecs
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 III-4-14 Qos
Note: It’s recommended that you configure the QoS in your router or switch instead of
NeoGate side.
5) Response Code
You can change the response code on NeoGate TA to the one you want before sending it
to the VoIP server. It helps the VoIP server understands better the exact call status, like
