Hi,

My PC application (192.168.1.127:5070) invites [email protected]:5060, who is account of a AVM FRITZ!Box Fon ata 1020 /firmware 11.04.01 (LAN connected, no registrar, no NAT, no STUN, username=max, password=admin).

Subsequently, the application tries to REFER the call to [email protected]:5070. The FRITZ!Box requires an authorization for a REFER and sends a "401 Unauthorized". The REFER is send again with authorization header. The FRITZ!Box answers with "400 Illegal Authorization header (10)".

Problem is that I don't see what's wrong with the authorization header. I used the following parameters for calculation the response:
- username=max
- password=admin
- realm=4DAA95B39CEF4D4DAD1C5CB6FAE64
- nonce=5300090F004C24962127B1537497E
- uri=sip:[email protected];uniq=4DAA95B39CEF4D4DAD1C5CB6FAE64

Any suggestions? Or does someone have an example of a successful authorized REFER session? Below are the session details. Feedback in German language is welcome!
