When a call is declined from iOS or Android app, the caller sometimes hears "Cancelled" and the call is dropped. 2 out of 10 test calls did this and only on calls to DID. Confirmed on multiple extensions. Looks similar to this thread but it is locked. https://www.3cx.com/community/threads/ios-app-decline-call-no-voicemail.45673/page-2 I'm on 15.5 SP1 with current app versions as of this posting. Has this issue been fixed?
