Hi Daniel,
Thanks for the response and link.  My config is broadly similar.

Presence is working over SIP (e.g. I can SUBSCRIBE and revive NOTIFY messages from the Kamailio Presence server)
and XCAP is working over HTTP (e.g I can GET, edit and PUT rls-service and resource-list documents into the XCAP table using curl over HTTP)

I don’t understand what the rls.so module is doing or how to debug.  I expect to PUT an resource-list document over the XCAP HTTP interface and then SUBSCRIBE to an eventlist over SIP…. at present I cannot SUBSCRIBE to the resource-list.  Any calls to rls_handle_subscribe() are getting the failure value back.

Any pointers on how to debug, or have I fundamentally misunderstood something?

Thanks

Hello,

I haven't used snom with rls and xcap, however, my working configs with xcap and based on the config snippet presented at:

  - http://lists.sip-router.org/pipermail/sr-users/2013-October/079988.html

If you are not familiar with, be aware that XCAP should be over http(s).

Should you be still stuck on something related to this topic, let us know if you already used a config like the one linked above, to follow up more on this.

Cheers,
Daniel

Hi
 I am struggling to figure out how to build and test an integrated presence server with Resource-List (rls.so) and XCAP (xcap_server.so).

I am confused about what is meant to happen and how to debug it.  Not sure if I am suffering from incompatibilities, configuration errors, or bugs…

I have not found an up to date guide on configuring an integrated presence, rls, xcap server so I have used old tutorials, module documentation and some course code review … but I’m pretty confused now!

I am using Snom phones and Jitsi (on Mac) to test.

I have a kamailio Registrar which proxies all presence messages to the separate kamailio 4.2 Presence server.

REQUIREMENT : Contact Presence
=============================
I would like to get a SUBSCRIBE from the Snom phone to subscribe to a contact-list resource list, and to receive a NOTIFY with all of the presence states for those contacts.  

Relevant snom settings?
Contact List URI:  this generates a SUBSCRIBE with event:presence 


I believe that:
==========
presence module should be managing the individual user presence and dialog states
xcap module should allow me to use HTTP / curl to edit the resource lists
rls module should be managing the mapping from a resource list subscription to the individual presence states and generating the aggregated NOTIFY messages.
each device should then be able to SUBSCRIBE to a resource list uri and then receive an aggregated NOTIFY for all of the watched entities.

The Subscription is showing up in the watchers table, not the rls_watchers table, so I believe it is being rejected by the rls_handle_subscribe() and then parsed by the presence module.  Is that correct?

There is noting in rls_watchers or rls_presentity tables.  Should there be?

I have a rows in the XCAP table for the Resource-List

relevant row in xcap table:

|  3 | org1a-contacts | *****.co.uk | <?xml version="1.0" encoding="UTF-8" standalone="no"?><resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists"><list name="team"><entry uri="sip:1002@****.co.uk"/><entry uri="sip:1001@****.co.uk"><display-name>bob</display-name></entry><entry uri="sip:1003@****.co.uk"><display-name>test1</display-name></entry><entry uri="sip:1006@****co.uk"><display-name>test1006</display-name></entry><entry uri="sip:1007@****co.uk"><display-name>test1007</display-name></entry><entry uri="sip:1008@h****.co.uk"><display-name>test1008</display-name></entry><entry uri="sip:1009@****.co.uk"><display-name>test1009</display-name></entry>    <entry uri="sip:1005@****.co.uk"><display-name>testing1005</display-name></entry>    <entry uri=“sip:org1a@****.co.uk"><display-name>testingorg1a</display-name></entry>    <entry uri=“sip:org1c@****.co.uk"><display-name>testingorg1c</display-name></entry></list></resource-lists> |        4 | sr-1490270411-10965-2 |      0 | /xcap-root/resource-lists/users/sip:org1a-contacts@****co.uk/index |    0 |


I have rows in the presence table for the entities that I want to track e.g.
                               |        |
| 2889 | org1c    | ****.co.uk | presence        | a.1490270411.10942.42.1083 | 1490277099 |    1490273499 | <?xml version="1.0
" encoding="UTF-8"?>
<presence xmlns="urn:ietf:params:xml:ns:pidf"
xmlns:im="urn:ietf:params:xml:ns:pidf:im"
          entity=“pres:org1c@*****.co.uk">
<tuple id="snom370-000413260935">
<status><basic>open</basic>
<im:im>Available</im:im>
</status>
<contact priority="1.00">sip:org1c@****.co.uk</contact>
<note xml:lang="en">Available</note>
</tuple></presence>

I am running kamaiio 4.2



Question : Should I have an resource-services row too? Or does rls.so infer the relationship using the URI?  When I use jitsi to manipulate its contact list it only inserts 2 rows into the xcap table and  I cannot get a SIP Subscribe to connect to that resource list either.

Question : What should the curl PUT commands and XML docs look like to build a valid RLS service (is there a good example anywhere)?

Question : Is there an example config or doc anywhere showing how to build integrated presence, rls, xcap?

Question : Has anyone got this working with Snom and or other handsets… the standards and implementations seem vague / inconsistent?


Note: There is another Snom setting (Extension Monitoring Call Pickup List URI:) which produces a SUBSCRIBE with Event:dialog but which should allow a button/lamp/callpickup/BLF for the buddy contact.  I’d like to get that working too, but recognise that rls.so does not handle dialog messages by default, so I’m starting with Presence...
