Hi, full agree with this bug report. Adding the devel maillist. More comments at the end of the mail:

Hi,
I'm using Kamilio 3.3.0 as registrar server. I`m using an outbound proxy so 'use_path' parameter or 'registrar' module is enabled.
According to RFC 5626, a re-registration from a specific combination of AoR, instance_id and reg_id must update the binding.
"" If the registrar receives a re-registration for a specific combination of AOR, and instance-id and reg-id values, the registrar MUST update any information that uniquely identifies the network flow over which the request arrived if that information has changed, and SHOULD update the time the binding was last updated. ""
In my installation this is not fullfilled as shown:
"" AOR:: jmillan Contact:: sip:jmillan@MY_IP;transport=ws;ov-ob=a570655c14 Q= Expires:: 181 Callid:: 1hgq3khalq2rzfr Cseq:: 108 User-agent:: JsSIP 0.1.0 Path:: sip:OUTBOUND_IP:9090;transport=tcp;lr;ovid=de0c0b9f,sip:a570655c14@OUTBOUND_IP:10080;transport=ws;lr;ovid=de0c0b9f;ob State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: tcp:KAM_IP:5060 Methods:: 783 Ruid:: uloc-50119d99-328e-1 Instance:: urn:uuid:38dce009-ae1f-4fd1-91dc-99ed9affddc1 Reg-Id:: 1 Contact:: sip:jmillan@MY_IP;transport=ws;ov-ob=1dd97b4d51 Q= Expires:: 193 Callid:: 1hgq3khalq2rzfr Cseq:: 110 User-agent:: JsSIP 0.1.0 Path:: sip:OUTBOUND_IP:9090;transport=tcp;lr;ovid=de0c0b9f,sip:1dd97b4d51@OUTBOUND_IP:10080;transport=ws;lr;ovid=de0c0b9f;ob State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: tcp:KAM_IP:5060 Methods:: 783 Ruid:: uloc-50119d99-3290-2 Instance:: urn:uuid:38dce009-ae1f-4fd1-91dc-99ed9affddc1 Reg-Id:: 1 ""
The scenario is such that when the client looses the connection with the Outbound Server, it reconnects and re-registers to Kamailio in order to replace registration and be able to receive in-dialog messages.
Receiving in-dialog requests should work since GRUU is also being used. The problem is that the new REGISTER (after UA disconnection) does not update the previous one (as this thread reports) so Kamailio still chooses the previous binding which does not work anymore.
Regards.
