well that means, that if I have a "bad" phone line (meaning poor 
quality) and I remove the "r", I will definitely have silence, when I 
call cell phone numbers and may have silence on calls to normal phones.

If I leave the "r" in the dial string, this removes the silence and adds 
the ring tone, with the disadvantage that I will even hear the ring tone 
on calls to busy numbers.

If that is true, the whole problem is related to the quality of the 
phone line, which prevents asterisk from getting the right status fast 
enough.

Stefan
