[asterisk-users] cisco 7960 not registering after * restart

[Louis-David Mitterrand]

Hello,

When I restart asterisk the cisco 7960/7940 phones (sip fw 7.5) fail to 
re-register themselves with asterisk, even though I put 
"timer_register_expires: 60" in SIPDefault.cnf 

Is there a way to have these phones register themselves every 60 
seconds?

Alternatively, can asterisk be made to "remember" its dynamic sip hosts' 
registration after a restart?

Thanks,
