Summary:                    [patch] Linksys SPA94x keep-alive reply replies to
wrong address
Description: 
It appears as though the 489 Bad Event response to the NAT keep alive event
responds to the local address, instead of responding to the NATted
address.
This causes Linksys phones to go amber (no registration) after a short
amount of time after placing calls.
Turning the Linksys NAT keep alive off is a workound.
