[Linphone-users] Number of incoming call has no international format

[address@hidden]

    Hi
    
    When I receive a phone call (SIP provider in Switzerland) I'm not
    able to see the name of the caller even though it's in the contact
    list.
    Most probably it's because the caller numbers has not international
    format in the notification window but the contact entry has.
    When I edit the contact with no international phone number format,
    I'm not able to dial it and it doesn't get recognized either.
    
    Is there any solution to this problem? Why is the incoming phone
    number not in a international format (+41 for Switzerland) has it
    something to do with my settings or the one of my provider?
    
    System: Linux Debian
      Linphone: Desktop 4.5.0-alpha.130+876fba46 - Qt5.15.2 (Source
      Build)
    
    
    Thanks for any help in advance
    Michael
