asterisk users - Jan 2005 - Cant receive calls after network goes down and up

Hi,
 
I have several Grandstream phones connected to Asterisk, some behind NAT and
others not. If I reboot all the phones, everything is fine. Should the
connection go down, and then come back again, those behind a NAT are still
able to make calls, but are unable to receive calls.
 
    -- Executing Dial("SIP/1239-ba74", "SIP/1242|60|t") in
new stack
Jan 12 23:45:19 NOTICE[21576]: app_dial.c:803 dial_exec: Unable to create
channel of type 'SIP' (cause 3)
  == Everyone is busy/congested at this time (1:0/1/0)
 
However, extension 1242 is still able to call 1239? 
 
Is this a configuration problem in Asterisk or in the phones?
 
Please help
 
Regards
 
David Norton

That's probably a timeout problem in the nat box.

What is the register interval in the grandstreams? The qualify=yes should
keep the connection alive as long as Asterisk is up, but if it goes down and
then comes back up, the phone has to re-register with Asterisk before
asterisk can keep the connection alive.
