Hello,
 
i try to use the devspecific function for whispering and monitoring calls. on a 32bit platform (32 bit tsp) the application works like a charm, but when moving to a 64bit platform i always get a tsp error "dwSize mismatch". 
 
version is 8.6
 
i guess there is some problem in converting the struct to the byte array, here is the relevant source code in c#, maybe someone has an idea. 
 
the struct:
 
 
    public struct CiscoLineDevSpecificStartCallMonitoring
    {
        public int m_MsgType;
        public int m_PermanentLineID;
        public int m_MonitorMode; //0= NONE, 1=SILENT, 2=WHISPER, 3=ACTIVE
        public int m_ToneDirection; //0=LOCALONLY, 1=REMOTEONLY, 2=BOTH, 3=NOTLOCALORREMOTE
 
    }
 
 
here is the initialization:
 

        var cisco = new CiscoLineDevSpecificStartCallMonitoring
        {
            m_MsgType =(int) CiscoLineDevSpecificType.SLDST_START_CALL_MONITORING,
            m_PermanentLineID = agentLine.PermanentId,
            m_MonitorMode = 2,
            m_ToneDirection = 2
        };

 
and here is the calculation to get the parameter byte array (where i assume the problem):
 

        private static byte[] GetBytes(CiscoLineDevSpecificStartCallMonitoring msgMonitoring)
        {
            var size = Marshal.SizeOf(msgMonitoring);
            var arr = new byte;
            var ptr = Marshal.AllocHGlobal(size);
 
            Marshal.StructureToPtr(msgMonitoring, ptr, true);
            Marshal.Copy(ptr, arr, 0, size);
            Marshal.FreeHGlobal(ptr);
 
            return arr;
        }

 
Thanks for all suggestions, would like to avoid to go back to a 32bit machine...

I have noticed the same issues.  If you switch from int to intptr that will be better for getting the code to run on 32 and 64.  For me this made the message lamp feature work in either.  That being said the monitoring functions all still fail with dword size errors when run on x64 against the 64 bit tsp or 8.x or 9.x.  When I debug the byte arrays they look like what I would expect, perhaps you can tell me if they seem wrong.
