Hi there,

I'm a .net developer and I prefer C#. But I'm a bit confused about finding the best SDK for building a SIP softphone. I have never developed any VoIP application before.
Can anybody recommend me a software for this?

During searching and learning about this topic, I have found an SDK called Ozeki VoIP SIP SDK and I read its softphone development documentation: http://voip-sip-sdk.com/p_333-voip-s...ment-voip.html It sounds good, but I need some confirmation from you, guys. Does anybody have any experience about this software? Or what else can be used to create a softphone?

Thanks, guys, thank you so much
