Thank you. Now I see the call of URL in freeswitch command prompt, but the website will be not triggered.

Got error [500] posting to web server
Retry will be with url.....


will be coming up.
It's interesting because if I call my URL with my browser that work and I can give them all kind of parameters that I want.

For example:

http://192.168.2.21/callrec.aspx
http://192.168.2.21/callrec.aspx?var1=test
http://192.168.2.21/callrec.aspx?var1=test&var2=test2

and so on all kind of callings worked and I can read all parameters.
But I don't understand why FS gives an error and can't call the website.
The logfile of iis show me 

2010-04-19 19:48:50 127.0.0.1 POST /callregister.aspx - 81 - 127.0.0.1 freeswitch-xml/1.0 500 0 0 0
2010-04-19 19:51:16 127.0.0.1 POST /callregister.aspx - 81 - 127.0.0.1 freeswitch-xml/1.0 500 0 0 2
2010-04-19 19:51:16 127.0.0.1 POST /callregister.aspx - 81 - 127.0.0.1 freeswitch-xml/1.0 500 0 0 4

Ok error 500 internal server error. But why error 500 if I call it with my browser that works perfect.

Thanks for your help.
