saturaday and today it worked but indeed I also had problems with called id on the same network. It would work for a few days than it would not work. Also 1 day last weeks I could not be reached at all for some hours (tested on different networks in belgium) than the next day no problem.

The question is always is this a UM problem or a network operator. I would guess something at UM because i did not have any of these problems in the past.-

I always have problems with one of my um+ (no caller id); the other works well:???:
