1)我们在SPA3102里要set adminstration password
2)在router里set port forward (TCP)to the IP of SPA3102
3) 然后 http://<router_ip>: <port_number> 就可以到SPA3102的界面了。
4)当出现SPA3102的界面后,再输入SPA3102 administration password就可以。
Server and ATA serve different functions. For main site with PSTN out, server will be the best choice. For other sites, need to balance the complexity in the setup and usage. I think soft client and ATA will be better.
