Incoming call number recognition from Remote Phone Book

[Attila]

Hey,

thanks for your explenation. So the question now is why on phone A the number is displayed with a +xxx and on Phone B is displayed with double zero like 00xxx?
while the caller is my celphone?

Thanks again.


Update: Problem Solved:
Afther I read Kevin's explenation again I checked the settings online on the server side and there is was. The caller ID number format was set to double zero for some of our voip acounts.

thx Kevin
