No DLL registration

Hi guys.

We would like to share with you how you can use VoIP SIP SDK for Windows without dll registration.
Open “c:\Program Files (x86)\ABTO Software\VoIP Video SIP SDK\MlSampleWindowCSDll”.
Copy AbtoPhoneDllWraper.cs your project and use it in the same way as it is in MlSampleWindowCSDll.
That is it. Enjoy it!
Of course, SIPVoipSDK.dll and other dll files from binary folder have to be included in your app setup.
You can find more useful information in our F.A.Q.
