I’m pretty sure this is a bug. I’m experiencing a similar (and I think related) problem also on 14.0.25.4. The problem is that the bug report got closed as a duplicate of a bug that was fixed in 14.0.25.2. But if you look at both bug reports, they are describing opposite problems. I think the fixing of one caused the other.
The initial problem which is not the same as yours: [FREEPBX-19520] "Too-Late Announce" is not playing under Find Me Follow Me. - Sangoma Issue Tracker
Your problem, but it is no longer being fixed: [FREEPBX-19796] Call Confirm Not Allowing Acceptance through Queues - Sangoma Issue Tracker
