Opal is h.323 and SIP Stack H323plus is a H.323 stack only.
They are very different in architect, Both h.323 feature set is similar and been ported between both stacks Codec Plugins generally can be use by both.
Best to look at the docs for both stack. API doc for OPAL is at: http://www.opalvoip.org/wiki/index.php?n=Main.APIDocumentation
Hope this helps,

hello everybody,
I want to know the difference between opal and h323plus in client side The two libs are all based on ptlib, and I think the two libs have the same function---h323 stack.
I have made one window application which is above opal library. And I want to use h323plus lib, and don't change the application interface. Is there any difference between the application interfaces of opal and h323plus. Thanks.
The question is very urgent to me. I'll appreciate your answers. And Please give me some valuable advice. Thanks.
Best regards
andrew
