Phonebook import on A T85

HI there

I'm using a csv file created in numbers to import my contacts to the Yealink. All Contacts and numbers are in. But when I try to dial it says "not found". The contact appears also in the list dialed numbers.

seems something is wrong with the format, but 00041 and +41 makes no difference.
The format of the cell in the numbersfile is text, the export is unicode -8

Any ideas?

thanks
Dom
