<nat/>
The parameters listed in the next table define port and IP address changes used in NAT traversal. The port
changes alter the port used by the system, while the IP entry simply changes the IP advertised in the SIP
signaling. This allows the use of simple NAT devices that can redirect traffic, but does not allow for port
mapping. For example, port 5432 on the NAT device can be sent to port 5432 on an internal device, but not
to port 1234.
Network Access Translation Parameters
Parameter
nat.ip 1
IP address to advertise within SIP signaling - should match the external IP address used by the NAT device.
nat.keepalive.interval
The keep-alive interval in seconds. Sets the interval at which systems sends a keepalive packet to the
gateway/NAT device to keep the communication port open so that NAT can continue to function. If Null or 0, the
system does not send out keepalive messages.
nat.mediaPortStart 1
The initially allocated RTP port. Overrides the value set for tcpIpApp.port.rtp.mediaPortRangeStart.
nat.signalPort 1
The port used for SIP signaling. Overrides voIpProt.local.port.
1 Change causes system to restart or reboot.
