There is now a Grandstream GXV3000 in my network (neat

videophones, I must say).
However, when someone sends a presence event through my server, the
grandstream responds with a SIP packet and additional XML info:
U 99.101.102.103:5060 -> 172.17.240.240:54330

The XML info is causing errors in the logs (which I've been ignoring for
now, but that's not really an optimal solution).
[...]
Other than forwarding presence information to a
presence-capable server
that understands the XML, is there anything I can do on the SER side to
Every correct XML parser should complain because the values of the
'uri' attributes are broken (double quotes and less-than sign).
ignore the XML stuff so I don't get a screen full
of error messages
every time a presence event comes through?
I wonder why the NOTIFY body is parsed at all?
