Description: I noticed that for some phones hints are not correctly set. Here is example from extensions.conf:
####################
[BLF]
exten => 218,hint,SIP/218&SIP/2181
exten => 301,hint,SIP/301
####################
Asterisk shows this statuses:

-= Registered Asterisk Dial Plan Hints =-

301@BLF : SIP/301 State:Idle Watchers 0

Thank you.

I am not quite understanding the issue. Based on what you posted, it looks like the hint is working for 301.

What is it that is being expected?

Extension 301 is unreachable, but Asterisk hint for that extension is set to Idle.
This behavior is happening to some of the extensions not all. I cannot find any connection for extension 301 that would explain this wrong behavior.
Expected behavior is if extension is unreachable that the hint for that extension is also set to unreachable.
I hope this is more understandable.

There are two definitions of 'status' at play here.

From the perspective of the SIP channel driver, 'status' refers to whether or not the peer in question can be contacted by any SIP message request. This results in five possible states:
* UNREACHABLE - we cannot contact the peer
* LAGGED - we can contact the peer, but the response time is greater then the maximum allowed (defined in sip.conf)
* OK - we can contact the peer, and the response time is within the allowed tolerance
* UNKNOWN - either no contact has occurred yet, or we simply don't know the status
* Unmonitored - no monitoring is occurring of the peer

In this particular case, we're determining whether or not we can contact the peer. That is not the same as an ExtensionState. ExtensionState is protocol agnostic, which means that the concept of a SIP peer - and whether or not it can be 'contacted' - doesn't apply. Hence why the mapping between the two values is not necessarily identical or 1 to 1.

That is a bit clearer.

So, you are saying that "core show hints" doesn't display the proper state. Is Asterisk Manager always correct?

Also, it looks like you are using realtime, correct?

Hi. Yes, I am using realtime sip users, hints are in extensions.conf.
I noticed one more thing. When I restart asterisk this always happens. Hint is set correctly when I call extension.
Example:
;;;;;;;;;;Asterisk sip show peer ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
CLI> sip show peer 301
Peer 301 not found.

;;;;;;;;;;;Asterisk core show hint 301 WRONG STATUS it should be Unavailable ;;;;;;;
*CLI> core show hint 301
301@BLF : SIP/301 State:Idle Watchers 0
1 hint matching extension 301

;;;;;;;;;;; Asterisk manager WRONG STATUS it should be Status: 4 ;;;;;;;;;;;;;;;;;;;
Asterisk Manager:

Response: Success
ActionID: 1
Message: Extension Status

Context: BLF
Hint: SIP/301
Status: 0
;;;;;;;; When I call extension 301 asterisk manager status is set correctly:;;;

Hello again. I found the what is causing problem with hints and i think that this bug shouldn't be closed.
I use realtime sip peers and wrong hint statuses were been shown for phones that had "ipaddr" column in sip table set to 0.0.0.0 . When I deleted 0.0.0.0 or update table with "UPDATE voip.conf_sip set ipaddr='' where ipaddr='0.0.0.0';" problem went away.
:)
