is it possible to connect a sip user from remote into my asterisk server in main office. im using n80i with no problem in main office through wifi
now when im out from office and stay in an internet hot spot id like my n80i to connect to my * at office so i could make out going calls or receive incoming calls
here is my ideal schematic diagram
n80i wifi conected (www-hotsopt/dynamic ip)<----->main office where * is behind firewall with static ip
what would be the pre requisite?
