Hi all,

We are investigating an issue with BLF whereby the BLF key on the subscribed phone does not always “turn off” after the call has ended. We have enabled force_single_dialog to keep things simple for debugging. The attached pcap is the result. The relevant stuff as I see it is:

· Packet #60 – UA sends a BYE

· Packet #62 – PUA sends a PUBLISH over loopback with a state of “terminated”

· Packet #65 – The PUBLISH is sent out to the subscribed UA as a NOTIFY with a state of “early”

This causes the BLF light on the phone to continue flashing.

We are running a version of Kamailio compiled from the HEAD of the current 4.3 branch.

Any ideas?
