Details - When the ims_registar_scscf module sends a Notify after a deregistration and the contact has q= parameter, the XML contains state terminated for the AOR, and for the contact the state is active.
<?xml version="1.0"?>
<reginfo xmlns="urn:ietf:params:xml:ns:reginfo" version="1" state="partial">
    <registration aor="sip:+351915639755@nl.intinfra.com" id="0x2aeaf52ebb80" state="terminated">
    	<contact id="0x2aeaf52ebdd0" state="active" event="registered" expires="3558" q="0.500">
    		<uri>sip:+351915639755@192.168.230.47:5060;ep=192.168.137.206:49856;transport=udp</uri>
    	</contact>
    </registration>
</reginfo>
When q= parameter is not added in the contact field, the XML in the notify contains the following information after deregistration, AOR is terminated and also contact id in the state terminated.
<?xml version="1.0"?>
<reginfo xmlns="urn:ietf:params:xml:ns:reginfo" version="1" state="partial">
    <registration aor="sip:+31652526347@nl.intinfra.com" id="0x2b3396aecd60" state="terminated">
    	<contact id="0x2b3396af1e60" state="terminated" event="unregistered" expires="0">
    		<uri>sip:+31652526347@10.38.102.75:49844;transport=tcp</uri>
    	</contact>
    </registration>
</reginfo>
The contact in the XML of the notify seems to be incorrectly constructed when q=.. used in the contact header.
Attached a patch which creates the correct contact info when the subscriber deregisters
