I found a similar issue it was a result of calling setRtpTcpRole
with a null SdpBody object when media negotiation had failed

Specifically I saw the problem in

SipConnection.cpp

The fix was to add a test for null pBody as shown below.


UtlBoolean SipConnection::prepareInviteSdpForSend(SipMessage* pMsg,
                                            int         connectionId,
                                            const void* 
pSecurityAttributes)
{
    UtlBoolean bRet = TRUE;
    SdpBody* pBody = (SdpBody*)pMsg->getSdpBody();

    if ( pBody  && ( RTP_TCP_ROLE_ACTPASS != mRtpTcpRole) )
    {
        pBody->setRtpTcpRole(mRtpTcpRole);
    }


The media negotiation had still failed!
