Hi,

I want to build my own softphone and I want to use one of the cheap
VOIP providers. If I want to use Vonage or Lingo should my software
support SIP or H.323?

Thanks,
John

Thanks for your post!

Do you happen to know of an SDK for Java or C# that can talk SIP?

Thanks,

I just saw an announcement that gjtapi (http://gjtapi.sourceforge.net/)
now has a SIP capability.
