RLS is not sending Notify on resource list updated - sr-users

18 Nov 2022

Hello,

I'm using Kamailio v5.6.2 with presence, presence_xml, xcap_server, and rls
modules.

I pushed 2 documents to the xcap server:

1. urn:ietf:params:xml:ns:resource-lists

<?xml version="1.0" encoding="UTF-8"
standalone="no"?>

<resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists">

<list name="friends">

<entry uri="sip:1001@example.com">

<display-name>1001</display-name>

</entry>

<entry uri="sip:1002@example.com">

<display-name>1002</display-name>

</entry>

</list>

</resource-lists>

2. urn:ietf:params:xml:ns:rls-services

<?xml version="1.0" encoding="UTF-8"
standalone="no"?>

<rls-services xmlns="urn:ietf:params:xml:ns:rls-services"
xmlns:rl="urn:ietf:params:xml:ns:resource-lists" xmlns:xsi="

<service uri="sip:1000+presence@example.com">

<resource-list>

"friends"]</resource-list>

<packages>

<package>presence</package>

</packages>

</service>

</rls-services>

I'm subscribing to presence event on rls-service

The RLS sends a NOTIFY immediately upon accepting the subscription
according to RFC 4662 and also the RLS is virtually subscribing to the
presence event on the 2 resources in the friends list

Now I’m changing the resource list using XCAP.

I’m sending a PUT request with a new document and I see that the change is
pushed to the DB but user 1000 is not receiving a NOTIFY with the updated
list.

This is the updated document:

<?xml version="1.0" encoding="UTF-8"
standalone="no"?>

<resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists">

<list name="friends">

<entry uri="sip:1001@example.com">

<display-name>1001</display-name>

</entry>

<entry uri="sip:1002@example.com">

<display-name>1002</display-name>

</entry>

<entry uri="sip:1003@example.com">

<display-name>1003</display-name>

</entry>

</list>

</resource-lists>

I see that Kamailio is virtually subscribing on 1003 (The newly added user)
but NOTIFY is not received.

Also tried to subscribe on xcap-diff event, and the subscription was
accepted successfully but no NOTIFY is received.

Am I missing something?

Thanks,

Joey
