Rick, we ran into BLF issues at a customer's site. It turns out that we were load balancing the calls across the Kazoo cluster out of multiple data centers. The replication delay and which cluster was handling each call was causing havoc with BLF. Once we pointed the user to just one instance, with failover to the other in case of an emergency, the BLF issue cleared up. It is because the same system is now sending the clearing the BLF notifications. I can get you a more technical explanation from my NOC team if necessary. Hope that helps.
