设置Router的Port TRiggering或Port forwardind

如果用Port Triggring, 则ATA可以用动态IP，即从DHCP获得IP。
下面是Port Triggering的具体的设置：
Name:pap2 enable:Yes protocol:UDP port raige:5060:5061 session chaining:TCP/UDP session interval:0 sec address repace:TCP/UDP active:Yes

Name:voice enable:Yes protocal:TCP port raige:16384:16482 session chaining:TCP/UDP session interval:0 sec address replace:TCP/UDP active:Yes


如用Port Forwarding则ATA必须用固定IP，ATA不能用DHCP，IP必须写入ATA，例如192.168.0.10.
下面是具体的设置：
name:pap2 port start:5060 port end:5061 ip:192.168.0.10 active:Yes

name: voice port start:16384 port end:16482 IP:192.168.0.10 active:Yes

另外ATA上必须选择所有的NAT Yes Available
