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:
Many thanks!
