[SR-Users] Entries in PUA List and RLS Watchers List

[Hugh Waite]

Hi,

I don't know what might cause exactly the issues you are seeing, but 
here's what I would do to track it down.

1. If no xcap documents exist on the system, the client will get a 404 
and should usually PUT some new (empty) documents.

Assuming these 'empty' documents exist, the following should happen when 
the client logs in.
a. When the SUBSCRIBE to presence.winfo arrives it should create a 
single entry in the 'active-watchers' table. It should show a single 
subscription to presence.winfo where the watcher and presentity URI are 
the same user.
c. When the SUBSCRIBE to RLS arrives, it should create a single entry in 
'rls_watchers'. As there are no contacts in the resource-list doc, there 
are no rls subscriptions.

My questions to try and debug would be:
1. Does the above happen when starting from a clean database and not 
having any contacts or external links in the resource-list?

2. If that works, can you add contacts directly to the resource-list 
(like below) and try again. Does that cause a problem? You should see 
entries in 'pua' and 'active-watchers' for the added contacts.

    <?xml version="1.0" encoding="UTF-8"?>
    <resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists">
         <list name="oma_buddylist">
             <entry uri="sip:160000 at example.com">
                 <display-name>160000</display-name>
             </entry>
             <entry uri="sip:160001 at example.com">
                 <display-name>160001</display-name>
             </entry>
         </list>
    </resource-lists>

3. Finally add the external documents and external anchors and try again.

I haven't personally used anything that uses the external anchors 
feature, but if it is only the external URIs that are causing the 
problem, kamailio may think it is subscribing to the same URI each time 
causing a recursive loop. This may be visible on a network trace taken 
on the loopback interface.

Regards,
Hugh
