xmpp-sip gateway videocall using freeswitch

I am trying to make a g开发者_Go百科ateway between SIP and XMPP domain. I have an environment with FreeSWITCH and OpenFire (FreeSWITCH is registered as a component in OF).

A video call between 2 SIP users work, but I can't establish one between SIP and XMPP client (which is connected to the OF).

Do you have any experience with XMPP-SIP gateways? What should I do to enable such a call?

You should try and find out if the FreeSWITCH mod-dingaling module and the XMPP server you are using support the same version of Jingle. That will be tricky because Jingle is still in Draft and implementations are likely to be idiosyncratic.

If you turn on FreeSWITCH verbose debugging you should get some kind of error message back about where the call is failing.
