    I received the register requests and did a quick test with master
    branch and all is fine - one contact. I checked and branch 3.3
    should have same patches.<br>
    <br>
    What exact version are you running? you said 3.x which is too broad
    -- instance support was added for 3.3.0 and you should run latest
    version (3.3.2 or latest git branch 3.3) as there were some fixes
    for minor releases.<br>
    <br>
    Cheers,<br>

                      <div>I have 3.x Kamailio with GRUU support. I see
                        SIP Instance in the contact. However, I see a
                        problem. When I kill the SIP client on a device
                        and restart, it sends registration on a
                        different port. The server instead of updating
                        the contact in user location table, is creating
                        a new contact for the same instance. Do I need
                        to turn on something to get the&nbsp;expected
                        behavior? Here is the output from kamctl ul
