address is not static. It is recommended that a static public
IP address is used with this system. Please contact your ISP
for more information.
External Refresh Interval
If External Host is configured, you can specify how often
should TG100 perform a DNS query on this host. The value
is specified in seconds.
Local Network
Identification
Used to identify the local network using a network
number/subnet mask pair when the system is behind a NAT
or firewall.
Examples 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”: Not get the IP address from
DHCP server.
Please refer to RFC1918 for more information.
NAT Mode
Global NAT configuration for the system.
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 Re-invite
By default, the system routes media streams from SIP
endpoints through itself.
If this option is enabled, the system will 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.
