So i don´t know whre the problem is. Please help

Write the number in international format. This is always the best choice, because later you will receive messages and those are using international format too. Also, status reports use international format.

It is possible to use a header To_TOA to define the format of a number, and there are also settings international_prefixes and national_prefixes available. See this for details.

This was the solution. I had to write the Phone Numeber in an international format. Now its working! Thanks a lot!
