sipcommunicator recieves internal server error for mobile network calls

Hello

i hope this mailing list is not the completely wrong place to take  
this, but i'm pretty sure i'd recieve some kind of answer from you  
long before the GMX-guys would do something :)

This is the problem:
I have a modified version of the sip communicator, which is only used  
to call some devices out there in the mobile network. This is pretty  
much overkill, i guess something along the lines of the shooter would  
have been more appropriate, but i quickly ran into problems with the  
authentication for my gmx-voip-account (also with sip.1und1.de) with  
them, and the communicator somewhat worked, so i trimmed it down to  
only place calls.

The devices being called were programmed so that they instantly hung  
up, but then do something else, of course.

Well, it worked for a while :)

But today when calling a cellular device, i get " 500 Internal Server  
Error" instead of the "180 Ringing" i was used to.

Strange thing is, when using XLite, i can phone the cellular, so i'm  
prone to think its not entirely the fault of GMX. See below for the  
logs.


My question now is: do i have to mail the people from gmx, or can i  
change something in my code so it matches XLite more and would work?
And if any of you would have some code handy, with which i could use  
a commercial sip provider to let a phone ring, that would be welcome,  
too. Or just tell me it _can_ be done with the shootist, maybe i can  
get it to work after all..


Tanks for reading,
Michael Capper
