Re: [sipxtapi-dev] SIPXTapi crashes

Hello Paul,

What actually causes this negotiation to fail?.....I am trying to integrate
GIPS voice component with SIPXtapi and after that its happening. If i use
SIPXmedia instead of GIPS, it works fine.

I have made changed in Mediaadapter project (Sipxfactoryimpl and
cpphonemediainterface files.

Regards,

Manoj

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!

Regards

Paul
