The application is close to ideal now. I really, really love the way I can change setting per person now... It's so cool to have espeak use English, German, Turkish or Czech language settings depending on the name of the person who's calling. That's so incrediby nice...........

... except it still doesn't work.

I still get the effect that the name espekcaller pronounces is not associated with the calling number in any way. In the log file, I see how it identifies the correct number for the call, and then it says "contact found" or something and lists the VCard of a contact that has nothing to do with this number; in fact, this contact doesn't even have a telephone number stored.
There's no hint in the log file why the application does this...
