CustomPresence state is not included in NOTIFY packets

Hello All,

I’m trying to set up the custom presence feature with PJSIP using the simple configuration below.

exten => _6XXX,1,Set(PRESENCE_STATE(CustomPresence:${EXTEN})=away,temporary,test)
same => n,NoOp(${PRESENCE_STATE(CustomPresence:${EXTEN},value)})
same => n, Dial(PJSIP/${EXTEN})
same => n,Hangup()

exten => 6001,hint,PJSIP/6001,CustomPresence:6001
exten => 6002,hint,PJSIP/6002,CustomPresence:6002
exten => 6003,hint,PJSIP/6003,CustomPresence:6003
subscribe_context = 'subscribe'

My device state subscriptions work just fine; device state updates sent through NOTIFY packets and subscribers are able to see the xml with the relevant information.

I can also query my custom presence states through CLI using the commands below:

*CLI> presencestate change CustomPresence:6003 "Dnd,upstairs,eating lunch"
Changing 6003 to Dnd

*CLI> core show hints
6003@default        : PJSIP/6003,CustomPre  State:Idle            Presence:dnd             Watchers  1

However the subscribers are not able to see any information regarding Custom Presence States on NOTIFY packets. The XML sent along with the NOTIFY packet has only device state info.

Also it may be worth mentioning that I’m not using Digium phones and I haven’t installed the DPMA.
I use a WebRTC browser phone.

According to the this Wiki page I should be OK to use this feature without a Digium phone as long as I can make use of the XML sent.

“When a SIP device is subscribed to a hint you have configured in Asterisk and that hint references a presence state provider, then upon change of that state Asterisk will generate a notification. That notification will take the form of a SIP NOTIFY including XML content. In the expanding panel below I’ve included an example of a presence notification sent to a Digium phone. This particular presence notification happened when we changed presence state for CustomPresence:6002 via the CLI command ‘presencestate change’.
The CustomPresence provider itself is device-agnostic and support for other devices could be added in. Or devices themselves (soft-phone or hardphone) could be modified to interpret the XML send out in the Presence State notification.”

As you can see above I am able to change/read custom presence states through Dialplan and CLI however I’m not able to send that information to subscribers.

I got creative and tried a combination of different configurations but was not able to change the result. Any help would be greatly appreciated.


The given presence information is only sent to Digium/Sangoma devices[1] on PJSIP.

Thank you for your swift response, I really appreciate it. It’s heart breaking that we can’t use this nice feature. It would help me quite lot. I should probably create another topic for this but if you don’t mind I will ask another question here; I’m working on a peculiar scenario where I’m trying to send the callerid of the caller to all my presence subscribers so that I can have a presence state such as “On the call with xxx”. Is there any other way I could achieve this? Could you please show me a direction?

The dialog-info+xml code provides information on who is at least calling, I don’t recall if it extends to being on call. There’s no other support for doing such a thing in NOTIFY requests without adding custom code.

Thanks a lot, I will take a look at that.
