What SDK's exist for Java and/or C# to support VOIP?

Archived from groups: comp.dcom.voice-over-ip (More info?)

Vonage does have a web service that lets you place calls. They call it Third
Party Call Control. Info is here:

When you place the call, it first rings your own phone. Once you answer, it
rings the called phone.
