Interval
Used to identify the local network using a network
number/subnet mask pair when the system is behind a NAT or
firewall.
Some examples of this are as follows:
“192.168.0.0/255.255.0.0”: All RFC 1918 addresses are local
networks;
“10.0.0.0/255.0.0.0”: Also RFC1918;
“172.16.0.0/12”:Another RFC1918 with CIDR notation;
“169.254.0.0/255.255.0.0”: Zero conf local network.
Please refer to RFC1918 for more information.
NAT Mode
Global NAT configuration for the system; the options for this
setting are as follows:
Yes = Use NAT. Ignore address information in the SIP/SDP
headers and reply to the sender's IP address/port.
No = Use NAT mode only according to RFC3581.
Never = Never attempt NAT mode or RFC3581 support.
Route = Use NAT but do not include rport in headers.
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 routing.
3) Codecs
We can choose the allowed codec in NeoGate TG, a codec is a compression or
decompression algorithm that used in the transmission of voice packets over a network or
the Internet. 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.
