[Kamailio-Users] [presence] use case of a user that doesn't un-REGISTER and un-PUBLISH

Hi Using kamailio v1.5 (trunk), I'm testing the following simple presence scenario where one user shutdowns his application without prior un-PUBLISH and un-REGISTER. 1) user A subscribes to user B presence. Both use X-Lite. 2) user B shutdowns his X-Lite (without doing un-REGISTER and un-PUBLISH of his presence information), 3) user B starts again X-Lite, registers and publishes his presence, from that point when user B updates his presence information, user A does not see the updates ! I've configured kamailio to use save("location", "0x04") instead of save("location") for incoming REGISTER but this does not help. Is there a way to clean presence DB tables properly when user B register again ? Regards, Pascal
