3.12.5.2 Proxy Behavior

  • Article

When a SIP proxy that logs dialog creation events processes a dialog creating request or final response to a dialog creating request that has an Ms-Correlation-Id header field present and the value in this field is a valid UUID, as defined in [RFC4122] section 3, it can record the value in the log. If the value is not a valid UUID, the proxy SHOULD ignore the presence of the header.
