Hi Federico and Anthony,

Were you guys able to come up with a solution for this? I had mine working for 
about a month without any problems. I'm running the git version from October 1, 
2011. I just ran into the same problem after changing my router since I changed 
my Internet connection from DSL to fiber optic. Reading the comments from this 
post: 
http://www.personal.psu.edu/wcs131/blogs/psuvoip/2010/10/using_freeswitch_to_add
_google.html
I guess this is an issue with Freeswitch having problems when there are Internet 
disconnections. I guess one way to solve this would be to change my router, but 
I don't really want to buy another ONT router, besides I don't even know if my 
ISP would let me use a different ONT since the ones that they provide are all 
"customized".
It is really hard to tell when it has disconnected. Even when typing "dingaling 
status" from the fs_cli, it will show AUTHORIZED when it is disconnected. The 
only way to tell if it's been disconnected is checking whether I can make calls 
or not.
To solve this ,without having to restart freeswitch I would "disconnect" 
(according to FS) from my gtalk profile typing "dl_logout gtalk" and reconnect 
with "dl_login profile=gtalk". I also had the idea to use the "cron" approach 
and thought this was going to be the solution to all my problems. Of course, I 
had to test what would happen if the cron job would happen to run in the middle 
of a call. I manually typed the commands on the fs_cli while I was on a call and 
my call did not die!! Great!! I had the solution to the problem!! I then 
finished the call and ooohh surprise!! I was suddenly disconnected from the 
fs_cli, FS would die, close unexpectedly and create a core dump.
I would really like to help to solve this so let me know if there's any way I 
can help out.
I would like to try the chat approach to see if that works. Did you figure out 
what is the right syntax to chat?

Greetings,

Ricardo
