I think the main question here is: how are you connecting Asterisk to the 
telephone system?

You mention that you're on DSL from Deutsche Telekom, but is the call going 
over this DSL link to soem SIP provider, who then connects you to the PSTN, or 
are you connecting Asterisk locally to the phone line via some ATA device?

In fact, it's probably worth outlining your hardware arrangement as much as 
possible:

 - what sort of telephone are you using - analogue or SIP?
 - where is your Asterisk server - on your local network, or hosted elsewhere?
 - how is Asterisk connected to the PSTN?
 - are the people you're talking to on analogue landline phones, mobiles, or 
SIP phones?
 - anything else you can tell us along these lines would probably be helpful.

Oh, and what's the *upstream* bandwidth of your Telekom connection?
