asterisk users - Feb 2013 - Google talk not (re)connecting after network down

Hi all,

I notice yesterday night while doing tests of uptime that if I unplug my 
network from the internet, then plug it back, my jabber still shows 
connection to google, but no outgoing calls are going out, and nothing 
is coming in (calls are going in google vmail since there is no 
connection to the pbx)

My way of restarting jabber was to kill asterisk and restart it.
I'm sure I could have unload then reload the module.

Is there any safe feature that can make sure that when Jabber shows 
CONNECTED , it *IS* actually connected ?

Thanks folks !
