Hi Alex,
Very pleased to hear that. 
I traced back your case and seems like we forgot to add your incident number to release note document. You could anyhow found following text from release note:
"If the trunk became active/inactive and sent the active/inactive event after this configuration change, CD could offer calls to incative trunks and ingore active ones."
That is refering to fix you are looking for. It could speak about SIP PING instead of active / inactive but that's how it is now.
