[SR-Users] One active registration per sip instance.

[Krishna Kurapati]

Hi,

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 expected
behavior? Here is the output from kamctl ul show.

Thanks
