407 Proxy Authentication Required problems with
I have configured auth-attributes on ITSP Session agent as well as on PBX Side session agent on the SBC.
auth-attributes
auth-realm example.com
username usernamehere
password ********
in-dialog-methods INVITE
I receive 407 Proxy Authentication Required from ITSP but the SBC just sends it back to the PBX instead of answering with a new INVITE with the credentials.I have updated the AUTH attributes under PBX side session agent. but still it getting failed. However i configured surrogate agent and it register successfully with the ITSP. Can you please advise how we can resolve this issue by SBC send the New INVITE along with the authorization header to ITSP.
