Just started with freeswitch and working my way through the user guide but cant find anything about this.

Basically i want to create a system so that when i travel overseas, from my mobile phone i can call freeswitch, then enter some code. hang up. freeswitch calls me back with a dial tone or maybe with some more menu options that then allows me to dial out...

I've tried some google searching, but i dont know the correct terms to search for... as i've said i've also read the menu and browsed around the wiki....

grateful for any pointers in the right direction
