你的意思是否，得一個IP address and 一個 router, 有一個IP01 and 一個 asterisk server。應該唔得，因為 sip and iax registration 用同樣的 ports. 如果少人用都還可以用 custom ports, 但係有時唔可應對唔同嘅 soft phone ， device ，voip trunk

你需要2 個或以上嘅 獨立 IP。

其實這問題我已經嘗試在一個 LAN解決，就是因為 port 的問題，所以唔可以應用對外。

如何你有2 個IP，就不如用一個 dual WAN router 處理。當設定為load balance 時，你在同一個lan segment 就可以唔需要改 ports 起 2 個 asterisks/IP0x/ATA。

你用邊款 router?

You may try to flash with dd-wrt firmware and then you should be able to use 2 WAN IP. I have a DD-WRT router but not yet have time to try. However, I am not sure if you can configure the load balance as easy as true dual wan router

你需要係 asterisk D config files 改

You will need the client know where to connect and by which ports.
For testing purpose, no problem. Real use, you may encounter difficulty because it is not only client connect to Asterisk server. Your Asterisk server also needs to connect to other VOIP providers.

So if you have two true IPs, better to go for a dual WAN router.

請問你用2 個 asterisks唔同 ports點樣互打？
