             Summary: chan_pjsip: In-dialog authentication not handled.
                 Key: ASTERISK-25131
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25131
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip, Resources/res_pjsip_session
    Affects Versions: 13.3.2
            Reporter: Richard Mudgett


When the remote peer requires authentication for in-dialog requests then re-INVITEs to the peer cause the call to be disconnected and other in-dialog requests to the peer like MESSAGE just don't go through.

Example scenarios:

Re-INVITE causes disconnect on incoming call because authentication is not handled.
{noformat}
Asterisk --- Peer
    <-- INVITE
    200 OK -->
    <-- ACK
    INVITE -->
    <-- 401 Unauthorized
    ACK -->
    BYE -->
    <-- 200 OK
{noformat}

In-dialog MESSAGE during incoming call fails.
{noformat}
Asterisk --- Peer
    <-- INVITE
    200 OK -->
    <-- ACK
    MESSAGE -->
    <-- 401 Unauthorized
    The in-dialog message is no longer tried.
{noformat}

Re-INVITE causes disconnect on outbound call because authentication is not handled.
{noformat}
Asterisk --- Peer
    INVITE -->
    <-- 401 Unauthorized
    ACK -->
    INVITE/w auth -->
    <-- 200 OK
    ACK -->
    INVITE -->
    <-- 401 Unauthorized
    ACK -->
    BYE -->
    <-- 200 OK
{noformat}

In-dialog MESSAGE during outgoing call actually succeeds.
{noformat}
Asterisk --- Peer
    INVITE -->
    <-- 401 Unauthorized
    ACK -->
    INVITE/w auth -->
    <-- 200 OK
    ACK -->
    MESSAGE -->
    <-- 401 Unauthorized
    MESSAGE/w auth -->
    <-- 200 OK
{noformat}
