What is the language is the source code written in. I see mention of Microsoft Product support. Is the application written in .net? If so, what version? Our company uses microsoft technologies whenever possible.

TeleFlow Server is entirely written in C++, apart from some functionality at its kernel, which is in C. <br> <br>All the source code has been developed by enGenic, and has been designed to compile against telephony hardware and engines provided by companies such as Intel/Dialogic, NMS, and AudioCodes. <br> <br>Is there something specific that is required as far as communications to others services go?

Most functionality is already covered in your solution out of the box. Our concern was more in regards to future extensibility when incorporating the solution locally as most development on our end is in C#. This doesn't mean that we wouldn't use the product as we are still evaluating it. Just something we have to consider. <br> <br>Thanks for the quick response.

That makes sense. We have had a history of working closely with our customers to make certain functionality can be leveraged between various systems. TCPIP messages (XML and so on), Databases, DLL calls, compiled in code, and the like are just some of the approaches we can use to promote interoperability.

On that note, is there any reason that function calls to .net managed code dlls wouldn't work? I wrote a dll for test purposes but it won't seem to load. It has one method called ReturnResponse that accepts a string value and returns a string value.

I also found this string regarding a seperate user needing similar functionality from vb6. <a href="http://devnet.engenic.com/index.php?action=vthread&forum=10&topic=229" target="_new">http://devnet.engenic.com/index.php?action=vthread&forum=10&to pic=229 </a> I also tried vb6 and ran across the same problem. I have tried using the System.Runtime.Interop and CCW (Com Callable Wrappers) all to no avail. Are there any plans to provide a seperate DLL Function object that will accept managed code dlls, vb6 dlls, or CCW based dlls. <br> <br>Thanks

TeleFlow can only call functions within you DLL, and cannot work directly with classes or objects in your code. The functions specifications must include the "Cdecl" calling convention. This is the most likely cause of your calling woes. <br> <br>Also, this thread has some advice on building DLL's that work with TeleFlow: <a href="http://www.engenic.com/devnet/index.php?action=vthread&topic=337&forum=10&page=-1" target="_new">http://www.engenic.com/devnet/index.php?action=vthread&topic=337&a mp;forum=10&page=-1 </a>
