Pjsua-2 Android-如何在通话时添加自定义头来邀请请求?

我想出来了。应将SipTxOption添加到CallOpParam:

    CallOpParam prm = new CallOpParam(true);
    SipHeader sipHeader = new SipHeader();
    sipHeader.setHName("Subject");
    sipHeader.setHValue("paid call");
    SipHeaderVector sipHeaderVector = new SipHeaderVector();
    sipHeaderVector.add(sipHeader);
    SipTxOption sipTxOption = new SipTxOption();
    sipTxOption.setHeaders(sipHeaderVector);
    prm.setTxOption(sipTxOption);
    call.makeCall(buddy_uri, prm);

SipHeader sipHeader = SipHeader();
sipHeader.hName = "Subject";
sipHeader.hValue = "34020000001320000001:0,34020000002000000001:0";

SipHeaderVector sipHeaderVector = SipHeaderVector();
sipHeaderVector.push_back(sipHeader);
SipTxOption sipTxOption = SipTxOption();
sipTxOption.headers = sipHeaderVector;
prm.txOption = sipTxOption;
