Hello Everyone! What i Have: `[root@FreePBX-FSI ~]# cat /etc/schmooze/pbx-version 6.12.65-31 [root@FreePBX-FSI ~]# asterisk -rvvvvvvv Asterisk 11.20.0, Copyright (C) 1999 - 2013 Digium, Inc. and others.` FreePBX was upgraded from 6.12.65-29 (initial installation and configuration was on this, and upgraded to -31 via script as descripbed in freepbx wiki - all fine) What is the problem: Having trouble with BLF hints and sip presence for a couple of extensions. All extensions are advertising states for other subscribed softphones fine, but a couple of them remain with hints IDLE and not changing to UNAVAILABLE when i terminate softphones (extensions get state from OK to UNKNOWN in ‘sip show peers’) Output of ‘sip show peers’, with disconnected extensions: ```auto FreePBX-FSI*CLI> sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status 401/401 (Unspecified) D Auto (No) Auto (No) A 0 UNKNOWN 402/402 (Unspecified) D Auto (No) Auto (No) A 0 UNKNOWN 403 (Unspecified) D Auto (No) Auto (No) A 0 UNKNOWN 404 (Unspecified) D No No A 0 UNKNOWN 405/405 172.16.50.221 D No No A 5060 OK (1 ms) 406 (Unspecified) D No No A 0 UNKNOWN 407 (Unspecified) D Auto (No) Auto (No) A 0 UNKNOWN 408 (Unspecified) D Auto (No) Auto (No) A 0 UNKNOWN ``` The extensions 401 and 403 are the problematic ones 405 is subscribed to monitor other extensions (MicroSIP, but doesnt matter, Eyebeam shows same result) Output of ‘sip show subscriptions’ : `Peer User Call ID Extension Last state Type Mailbox Expiry 172.16.50.221 405 c26d6f0c2fcf400 403@from-intern Idle pidf+xml 000600 172.16.50.221 405 28d09e3062e7432 405@from-intern Idle pidf+xml 000600 172.16.50.221 405 f5ceca197e7f4e5 *46*402@from-in Idle pidf+xml 000600 172.16.50.221 405 fd58110296024eb 402@from-intern Unavailable pidf+xml 000600 172.16.50.221 405 98b212e2f89247c *46*403@from-in Idle pidf+xml 000600 172.16.50.221 405 f7fca66ebaf846d *46*401@from-in Idle pidf+xml 000600 172.16.50.221 405 68a9a137fc85437 408@from-intern Unavailable pidf+xml 000600 172.16.50.221 405 fa51bdf2c3f140e 401@from-intern Idle pidf+xml 000600 172.16.50.221 405 6a5a6a4a45d04a9 407@from-intern Unavailable pidf+xml 000600 172.16.50.221 405 52d50cabc863414 404@from-intern Unavailable pidf+xml 000600 172.16.50.221 405 e225561ffca94a9 406@from-intern Unavailable pidf+xml 000600 172.16.50.221 405 51d52e679d2146c *46*404@from-in Idle pidf+xml 000600 12 active SIP subscriptions` (Yes, i also monitor ‘queue pause’ states) As you can see 403@ and 401@ remain idle even with no connected peers. When i connect 401 or 403 they notify Ringing, In Use and other states (Except UNAVAILABLE) just normal as it must be. So, for now, I tried removing those extensions and re-creating them - no effect. Restarts, reloads - no effect. The trouble was before i upgraded freepbx - so upgrading also didnt solve the problem. ‘core show hints’ output: `401@ext-local : SIP/401&Custom:DND40 State:Idle Watchers 1 403@ext-local : SIP/403&Custom:DND40 State:Idle Watchers 1 402@ext-local : SIP/402&Custom:DND40 State:Unavailable Watchers 1 405@ext-local : SIP/405&Custom:DND40 State:Idle Watchers 1 404@ext-local : SIP/404&Custom:DND40 State:Unavailable Watchers 1 407@ext-local : SIP/407&Custom:DND40 State:Unavailable Watchers 1 406@ext-local : SIP/406&Custom:DND40 State:Unavailable Watchers 1 408@ext-local : SIP/408&Custom:DND40 State:Unavailable Watchers 1` I dont understand why this is happening, because i tried to make configuration of pbx clean as possible, from GUI (didn’t touch settings i don’t know/don’t need). New extensions which i create don’t have such problem, only those two 401 and 403. Any help will be apreciated, thank you! ---

[quote=“mkozusnik”]I don’t know FreePBX, but is ext-local included in from-inter…? [from-internal-sip] ;I assume include =\> ext-local[/quote] included ext-local in [from-internal] No change. The interesting thing is that only those 2 extensions 401 and 403 don’t go in Unavailable state when sip show peers = UNKNOWN… other 402, 404,405 etc… anything OK with them, even if contexts differ. But other states are advertising just normal (Ringing, In Use and so on…). When i create extension from GUI, by default the Context field is filled with the ‘from-internal’… I tried to change this to ext-local: for 401 - the one with problem for 405 - the one which subscribes to monitor states (in that case i dont more see the queue pause states) Still no effect…
