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: Code:
SIP Rx: UDP 193.xx.xx.xx:5060 -> 192.1xx.1xx.2xx:5084 BR Stefan |
In your SIP URI for the line, do you have the credentials selected under the "Registration:" drop down menu?

I am facing the same problem, does anyone have a tip or solution?
