Examples of javax.sip.header.TimeStampHeader

javax.sip.header.TimeStampHeader

The Timestamp header field describes when the UAC sent the request to the UAS. When a 100 (Trying) response is generated, any Timestamp header field present in the request MUST be copied into this 100 (Trying) response. If there is a delay in generating the response, the UAS SHOULD add a delay value into the Timestamp value in the response. This value MUST contain the difference between the time of sending of the response and receipt of the request, measured in seconds. Although there is no normative behavior defined here that makes use of the header, it allows for extensions or SIP applications to obtain RTT estimates, that may be used to adjust the timeout value for retransmissions.

For Example:
Timestamp: 54 @author BEA Systems, NIST @version 1.2

        if (cid != null)
            callId = cid.getCallId();
        String firstLine = message.getFirstLine().trim();
        String inputText = (logContent ? message.encode() : message.encodeMessage(new StringBuilder()).toString());
        String tid = message.getTransactionId();
        TimeStampHeader tsHdr = (TimeStampHeader) message.getHeader(TimeStampHeader.NAME);
        long tsval = tsHdr == null ? 0 : tsHdr.getTime();
        logMessage(inputText, from, to, sender, callId, firstLine, null, tid, time, tsval);
    }

        if (cid != null)
            callId = cid.getCallId();
        String firstLine = message.getFirstLine().trim();
        String inputText = (logContent ? message.encode() : message.encodeMessage(new StringBuilder()).toString());
        String tid = message.getTransactionId();
        TimeStampHeader tsHdr = (TimeStampHeader) message.getHeader(TimeStampHeader.NAME);
        long tsval = tsHdr == null ? 0 : tsHdr.getTime();
        logMessage(inputText, from, to, sender, callId, firstLine, null, tid, time, tsval);
    }

        if (cid != null)
            callId = cid.getCallId();
        String firstLine = message.getFirstLine().trim();
        String encoded = (logContent ? message.encode() : message.encodeMessage(new StringBuilder()).toString());
        String tid = message.getTransactionId();
        TimeStampHeader tshdr = (TimeStampHeader) message.getHeader(TimeStampHeader.NAME);
        long tsval = tshdr == null ? 0 : tshdr.getTime();
        logMessage(encoded, from, to, sender, callId, firstLine, status, tid, time, tsval);
    }
