Default SIP Trunk - outbound problems

Dear Forum!

I have a problem with a SIP-Trunk on outbound side. The registration (which is mandatory) is sucessful, but when i start a call, there comes a packet "407 - Proxy Authentication required" after the INVITE ans TRYING packet.

My ITSP tells me that my IPO obviously doesn't send the authentication back (Ack + 2nd invite), but I have no plan, where I can this configure. I already tried several configurations for hours without success.

Does anyone have some ideas?

Sip-Protocol is here:

SIP Rx: UDP 193.xx.xx.xx:5060 -> 192.1xx.1xx.2xx:5084
                    SIP/2.0 407 Proxy Authentication Required
