Well, something's not working as "I expect it to". My GXP2000 phones have re-registration timeout of 2 minutes.

In my example below, extension 4061 is unplugged (so obviously it won't re-register, ever). Meanwhile, the other GXP2000 phones keep seeing 4061 as "on-line" (green led).
This happens with Asterisk 1.4.24.

If I use Asterisk 1.2, the green LED turns red within a few seconds.

My guess is that Asterisk is not sending the device state, or it's not correctly detecting that the phone has not re-registered.

I might not be interpreting the "hints" logic correctly, but I suppose that if a "sip show peer" reveals that the extension is not registered (when it was before) then Asterisk should send out a message to all subscribed phones so that their BLF can be updated.

As you can see below, 4061 is switched off, isn't physically online anymore, but all BLF LEDs are green.

Why is this?

PS: (I don't understand why 4061 at ext-local has "State:Idle")

Thanks,
