	If you're gonna top post...so am I.
	
	I think you misunderstand what qualify is/does.  It appears that you believe that qualify=1000 means that it'll send out a qualify packet every 1000ms.  This isn't an unreasonable assumption, but it is wrong.  The qualify=1000 means that Asterisk will wait 1000ms for the device to respond to the qualify packet.  If after 1000ms there is no "yes, I'm here" packet, then it will be considered UNREACHABLE.  Qualify packets are sent out at a set interval, which, as you can see, is 60 seconds.  If the device was previously determined to be UNREACHABLE, the qualify packets will then be sent out every 10 seconds instead.

	In that case, if I set qualify=1000, and it still polls every 60s, then how can it consider it unreachable at 1000ms?

	        The value that qualify takes is the maximum time to accept before considering the device unreachable. If I set qualify to 200ms, and my device's qualify time is 250ms then the device will be considered unreachable.

	        Yes, you can. voip-info.org is a wiki that anyone can update/change/modify.
