    Hello,
    I have installed the 9.0.1.10000-35 from a scratch.
    I have tried again the testing ofthe notification functionality, for me this is still not working. I did the following:
     
    1. created a phone,
    2. send axl:doNotificationRegister (notification host)
    3. send axl:doNotificationObject (phone, subscribe)
    4. changed something on the phone via cucm gui

    But I cannot see any notification from the cucm on the notification host(with tcpdump), from which the ip was mentioned in the axl:doNotificationRegister Request.
    The cucm can ping the notification host, so this cannot be a network problem.
    The cucm knows about the change I made, I can request these changes either with:
    1. axl:executesqlquery   select * from axldbchangequeue
         <ns:executeSQLQueryResponse xmlns:ns="http://www.cisco.com/AXL/API/9.0">
             <return>
                <row>
                   <pkid>fa90ee20-7291-7499-2b9c-0707047d0af0</pkid>
                   <vendorConfig>
                      <pkid>99624bec-5c9d-678f-a34f-22c82617ecf6</pkid>
                      <name>SEP010203040506</name>
                      <operation>Update</operation>
                   </vendorConfig>
                   <clientsubscribed>6fa39138-3b4e-885c-3858-abcccfebbdc0</clientsubscribed>
                   <entrystarttime>1343895325</entrystarttime>
                   <mask>00000000000000000000000000000100</mask>
                   <tkchangenotifysubscribe>2</tkchangenotifysubscribe>
                </row>
             </return>
          </ns:executeSQLQueryResponse>
    2. Or with axl:getNotificationChange: the response is
          <ns:getNotificationChangesResponse xmlns:ns="http://www.cisco.com/AXL/API/9.0">
             <changeNotification>
                <objectLists>
                   <objectList>
                      <object>Phone</object>
                      <count>1</count>
                      <changedObject><![CDATA[<pkid>99624bec-5c9d-678f-a34f-22c82617ecf6</pkid><name>SEP010203040506</name><operation>Update</operation>]]></changedObject>
                   </objectList>
                </objectLists>
             </changeNotification>
             <pollingInterval>300</pollingInterval>
             <pollingStartTime>1343895981</pollingStartTime>
          </ns:getNotificationChangesResponse>

    As you wrote, I would expect when I make a change an cucm gui, I would get a change notification packet on the notification host, or am I wrong with that ?
    Can you support me with that ?
    Kind regards,
