New issue 205 by [email protected]: Problem with 407 proxy authentication in b2bua appliation
http://code.google.com/p/sipservlets/issues/detail?id=205

What steps will reproduce the problem?
The flow I intend to implement is the following:

Client B2BUA SIP Trunk

     |      INVITE (SDP)         |                           |
     |-------------------------->|                           |
     |      100 TRYING           |                           |
     |<--------------------------|                           |
     |                           | INVITE (mod SDP)          |
     |                           |-------------------------->|
     |                           | 401 Unauthorized          |
     |                           |<--------------------------|
     |                           |      ACK                  |
     |                           |-------------------------->|
     |    401 Unauthorized       |                           |
     |<--------------------------|                           |
     |      ACK                  |                           |
     |-------------------------->|                           |
     |      INVITE (SDP) W/AUTH  |                           |
     |-------------------------->|                           |
     |                           |  INVITE (mod SDP) W/AUTH  |
     |                           |-------------------------->|
     |                           | 200 OK (SDP)              |
     |                           |<--------------------------|
     | 200 OK (SDP)              |                           |
     |<--------------------------|                           |
     |      ACK                  |                           |
     |-------------------------->|                           |
     |                           |      ACK                  |
     |                           |-------------------------->|


In the B2BUA I don't have (and I don't want) to store the user credentials, so I just copy the authentication headers from one side to the other.


The problem I am getting is that the second INVITE with the authentication header does not belong to the same sip app session/sip session than the original so I am not able to find the session from the previous INVITE, so I am not able to create the new INVITE with the same call-id/from tag as the previous one.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
