Hello,
I think the point ist that you use the IP of your proxy as the realm instead of your domain in X-Lite. You can see it in the call-ID in your messages: -------------------- SEND >> 192.168.1.2:5060 REGISTER sip:192.168.1.2 SIP/2.0 Via: SIP/2.0/UDP 192.168.1.203:5060 From: sip:1000@192.168.1.2 To: sip:1000@192.168.1.2 Contact: "JesusR" sip:1000@192.168.1.203:5060 Call-ID: 854E48C84C104A5DB92CE4A65ABC2406@192.168.1.2 CSeq: 31483 REGISTER Expires: 500 User-Agent: X-Lite build 1016 Content-Length: 0 -----------------------
Notice the call-id is xxxx@192.168.1.2 but not xxxx@voztelecom.net. However, in the 401-challenge which you received the realm is "voztelecom.net":
---------- WWW-Authenticate: Digest
algorithm=MD5,nonce="3f1c562000000000dded3e97ed7f89d3722ff12d3704a884",realm ="voztelecom.net" -------------
I think you should change your realm in X-Lite from 192.168.1.2 to voztelecom.net and everything will be ok. Otherwise, the X-Lite will treat the 401 response as an illegal challenge and won't send back his credential.
Best regards
