Are Lingo and Vonage H.323 or SIP?

Oct 23, 2004 3 Replies

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, John

I just saw an announcement that gjtapi

formatting link
now has a SIP capability.
