We have one Android phone with the Mitel UC Advanced app (5.1.34.20409 v124) who is getting "phantom calls" on his soft phone from number 100 at strange hours like 3 AM.
There is no record of these calls, or the calling number, anywhere - not in the call logs, not in the server logs.
There is no "100" assigned to any phone/ extension etc.
The only record we have is the user telling us that this is happening, and this AM he showed me in "Recent Apps" where it showed a small screen cap with the number 100 calling. We had our tech in from the company who installed, and they can find anything.
Has anyone ever seen anything like this?
