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”: not get the IP address from DHCP server
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 Re-invite
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.
Configure SIP Codec Settings
Navigate to
Gateway > VoIP Settings > SIP Settings > Codec
to configure the SIP codec settings.
