Hello,
I am using ZOIPER mobile and when I receive an external call I only see a "10000" in the display of the speakerphone.
It has worked formerly, as the phone number or the name (if exists in the contacts). But since a while it does not work - maybe I have changed any setting and hasn't recognized that this ends up in this way.
Unfortunatly I do not know, maybe which setting does work so, that instead the caller-id /name a "10000" appears?
Karl
