BLF status for INACTIVE/UNAVAILABLE (Asterisk PBX)

Hi,

I can see you are actually a Snom partner so I suggest you raise a private ticket, and not a public Community thread, so we can investigate better.

Anyway, since this can help other people: the phone cannot see if another phone is turned off or in a DND state for example, the BLF are based on some Notify SIP messages coming from the PBX.

When the BLF is configured the phone sends a Subscribe message to the PBX, asking for updates via Notify for that extension.

Usually the PBX sends different updates (bury, ringing or idle for example) when a phone is ringing or in a call or in idle state.

There is no direct way to know if a phone sets itself on DND or is powered off on the phone with the active BLFs, the only way could be the PBX sending a specific Notify, but that usually doesn't happen because even the PBX doesn't know the state of the phone.

As said, for further investigation, please raise a private ticket.

Thank you

Hi Gianmaria, 

I solved the problem using this how-to based on XML definitions adding the traslation for Unavailable as following

HOW TO KB: https://service.snom.com/display/wiki/HowTo+-+Extension+Monitoring+-+Asterisk+Presence

<general type=”AsteriskPresenceField”/>
<!–
Initialization:
Here we define some variables used in the XML
subscr_ext: this the extension of the SUBSCRIBE target
subscr_proxy: this is the domain part of the SIP uri to SUBSCRIBE
pickup_code: the pickup code to add in front of the extension in order to pickup the call
subscr_uri: will be created sip:$(subscr_ext)@$(subscr_proxy) this is the SUBSCRIBE URI
–>
<initialization>
<state value=”initial”/>
<!– PLEASE EDIT THE “value” ATTRIBUTE WITH THE RIGHT EXTENSION –>
<variable name=”subscr_ext” value=”123“/>

<!– PLEASE EDIT THE “value” ATTRIBUTE WITH THE RIGHT PROXY IP ADDR –>
<variable name=”subscr_proxy” value=”172.16.199.2“/>

<!– PLEASE EDIT THE “value” ATTRIBUTE WITH THE RIGHT PICKU CODE –>
<variable name=”pickup_code” value=”**“/>

<!– DO NOT EDIT –>
<variable name=”subscr_uri” value=”sip:$(subscr_ext)@$(subscr_proxy)”/>
</initialization>

<!– Define the kind of SUBSCRIBE –>
<subscription type=”presence” to=”<$(subscr_uri)>” for=”$(subscr_uri)”/>

<!– Verify the validity of the NOTIFY –>
<NotifyParsingRules type=”applies”>
<level1 translates_to=’OK’>/presence/tuple/contact[.=”$(subscr_uri)”]</level1>
</NotifyParsingRules>

<!– set the monitored extension state –>
<NotifyParsingRules type=”state”>
<!– if <ep:away/> tag is present se the status to “Away” –>
<level1 translates_to=”Away”>/presence/pp:person/status/ep:activities/ep:away</level1>
<!– when the status is closed set it “Offline” –>
<level1-1 translates_to=”Offline”>/presence/tuple/status/basic[.=”closed”]</level1-1>
<!– when the status is Unavailable set it “Offline” –>
<level1-2 translates_to=”Offline”>/presence/note[.=”Unavailable”]</level1-2>
<!– if <ep:busy/> tag is present se the status to “Busy” –>
<level2 translates_to=”Busy”>/presence/pp:person/status/ep:activities/ep:busy</level2>
<!– if <note> content is “Ringing” set the status to “Ringing” –>
<level2-1 translates_to=”Ringing”>/presence/note[.=”Ringing”]</level2-1>
<!– if <note> content is “On Hold” set the status to “Holding” (the phone is holding another call) –>
<level2-2 translates_to=”Holding”>/presence/note[.=”On hold”]</level2-2>
<!– if status is open set it as “Registered” –>
<level3 translates_to=”Registered”>/presence/tuple/status/basic[.=”open”]</level3>
</NotifyParsingRules>

<action>
<!– Dial the pickup code only in Ringing (dial is for backward compatibility) –>
<dial target=”$(pickup_code)$(subscr_ext)” when=”on press” states=”Ringing”/>
<invite target=”$(pickup_code)$(subscr_ext)” when=”on press” states=”Ringing”/>
<!– Dial the extension when Registered –>
<dial target=”$(subscr_ext)” when=”on press” states=”Registered”/>
<invite target=”$(subscr_ext)” when=”on press” states=”Registered”/>
<!– Nothing in all others status –>
</action>
