the above error message means that you try to handle an unsupported 
presence event. The subscribe is sent for MWI in this specific case, so 
it should be forwarded to Asterisk if you keep the voicemails there.

The presence_xml module is able to handle the events presence and 
presence.winfo. The presence module is the common framework for the 
other presence_* modules.

There is presence_mwi that should be able to handle the event 
'message-summary'. However, if you don't get the presence working for 
two x-lite softphones, the error is somewhere else -- the above message 
does not affect the SIMPLE status presence part.

The 'tab' is printed from the C sources, in the debug message, it is not 
the cause for the issue.

You have to watch the SIP traffic and see if the SUBSCRIBEs and 
PUBLISHes are replied properly. Then check if after a PUBLISH a NOTIFY 
is issued.


Cheers,
Daniel
