    * RECOMMENDATION:                                              *
    ****************************************************************
    The SIP container doesn't detect a case where there are two or
    more responses with the same to-tag in proxy mode, which is
    forbidden according to RFC 3261.
    

Problem conclusion

  • The fix lets the SIP container detect a situation where there
    are multiple responses to a proxy with the same to tag. In
    this case the container generates an error response and prints
    a warning. The error response to be generated is defined via
    the following custom property:
    "generated.container.error.on.to.tag.duplication".
    If the custom property isn't defined or set to 0 - the fix will
    be disabled.
    The valid values of the custom property are error codes
    between 3xx-6xx.
    Instruction of how to set SIP custom properties on V8.5.5 are

    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.10 and 8.5.5.4  Please refer to the
