I suspect this may in fact have been the cause of your problem.

Firstly, I notice that tel.t-online.de has a non-trivial DNS entry:

$ host tel.t-online.de
tel.t-online.de is an alias for ims.voip.t-ipnet.de.
ims.voip.t-ipnet.de is an alias for ims001.voip.t-ipnet.de.
ims001.voip.t-ipnet.de is an alias for b-epp-001.isp.t-ipnet.de.
b-epp-001.isp.t-ipnet.de has address

Secondly I find forum entries from people observing that either the IP address 
changes from time to time, or even that Telekom's DNS servers do not give the 
same result as root name servers:



Certainly, with allth eother information you gave, if the IP addresses at both 
ends stayed the same, I wouldn't expect an Asterisk restart to be necessary.



Your work is both good and original.  Unfortunately the parts that are good 
aren't original, and the parts that are original aren't good.
