I have a company and want to have a webphone so our customers could reach us easier. I found this site: http://www.voip-sip-sdk.com/
It is about an SDK called Ozeki VoIP SIP SDK and the pages describe how one can develop an own webphone. Unfortunately, I am not a technical oriantated person and do not have a C# programmer at the company yet.
My question is that has anyone here tried this program previously?
I am really interested about personal experiences.
