I have 2 Grandstream HT-286 devices and an Asterisk server. The * Server is not using NAT and has port 5060 opened up. One HT-286 is using traditional NAT and the other HT-286 is behind a residential DSL router/firewall. I have the HT-286 setup as the "DMZ Host" in the router/firewall so that all incoming connections are forwarded to the HT-286.
HT-286-1 ====== NAT FW ====== * Server ======= Router/FW ====== HT-286-2 In the setup for HT-286-2 , I have filled in the "Use NAT IP" field with the public IP for that location. I did the same thing for HT-286-1 and then I mapped a public IP to its private IP in the NAT FW. At this point, the two devices can call each other without any problems. I want to use the HT-286 for our traveling users who will never know what their IP is. When I remove the "Use NAT IP" entry on HT-286-1 as well as remove its direct IP mapping from the NAT FW, HT-286-1 can register with the * Server, but when I try to call HT-286-2, all I get is silence. If I do a 'sip show channels' it shows that the call is connected. Here is what I have in my sip.conf for these two units: [305] type=friend host=dynamic nat=yes qualify=100 [307] type=friend host=dynamic nat=yes qualify=100 Has anyone used these units in this scenario? Does anyone have any hints as to what I can try to get this working? Your help is much appreciated.
