Summary:                    Re-registration of SIP gateway sometimes occurs
after the scheduled delay which causes gateway to see asterisk as unregistered
Description: 
Note: the version reported by asterisk is 1.6.2.5 (not found in the product
version field of Mantis)

We have this problem on several asterisk installations.
We have some external SIP gateways we register to with a time-out of 120
seconds
Asterisk schedules a re-register every 105 second which is fine.
However, a few times a day, the re-registration occurs too late. This has
the side effect of becoming invalid for the outside gateway point of view.
On that outside gateway we have some specific rules in case asterisk is no
more registered, so this problem causes missed calls if they occur within
that "unregistered" period

Asterisk does not seems to be busy when the late re-registration occurs.
