[SR-Users] RLS is not sending Notify on resource list updated

Thu Dec 1 15:02:40 CET 2022

Have you confirmed if the NOTIFY is sent? Attempted to be sent? Noticed you said "but no NOTIFY is received"

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">

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

</entry>

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

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

</entry>

</list>

</resource-lists>

</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

  <resource uri="sip:1002 at example.com"/>

</list>

--1W1NaaaIIq6dOtLRXODFwqmC--

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 at example.com">

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

</entry>

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

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

</entry>

<entry uri="sip:1003 at 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
