How to get H.239 working as SIP server, not found in Asterisk or Yate or SipX or FreeSwitch

I was writing a small Java, application for peer to peer using SIP, which will be handling H.239 like all other common standards. But while working i wanted to have a Server who supports it to rely on. But so far i tried with Asterisk/Yate/SipX/FreeSwitch, and none does or allow this feature yet.

So, my question is for further testing and making my application compatible with SIP servers. Which SIP server i can use to test H.239?

Thanks a lot in advanced.

Follow up:

• Hammering my head, h.239 is a nightmare, if you are a developer dreaming SIP ( none can do that: asterisk, yate, freeswitch, sipx, openSIP, etc etc)

• Protocol must be, SIP (BFCP), H.323 (H.239), ISDN (H.230)

• No where in international standard found SIP will not do that, as SIP is protocol, so is H.323/ISDN, existing hardware does and there specification says following:

  The Presentation function and the Dual Video function support videoconferencing over both IP (H.323 protocol) and ISDN (H.320 protocol), or a combination of the two. Both functions can also be used in H.235 encrypted communication for when secure videoconferencing is required.

• If you read this article, somehow by mistake, from my experience the only advise would be, make sure what you are up to!! otherwise you will just buy all those www.google.com fastest search engine results, full of confusing hardwares, and get trapped to fine tune with your voip switch which is mostly now a days SIP.

• Get the dream out of your mind to have H.239 in SIP, thats not gonna work
• I开发者_开发技巧 wonder why the hell SIP was really necessary?

SIP shouldn't even be working with H.239. H.239 is the dual video specification that is used by H.323. It is negotiated on top of H.245 messages. SIP doesn't have H.245 - it uses SDP instead, so I can't see how you can achieve what you are trying to do.
