Hi all
I use sipp tool accompanying opensips server to generate normal SIP traffic. I successfuly enable authentication in opensips; added some users in database and performed authentication proccess in register and invite requests. I see valid authentication as username and passwords are valid and failure in authentication as password is invalid. After sending first invite and receiving 407 (proxy auth req) message; In my scenario an Invite message is sent with authentication header containing valid nonce. My problem is that when URI of re-Invite request is invalid I receive 407 instead of 404 (not found).
I'm so grateful about any help.
This is my opensips config file (opensips.cfg):
