How can I voice chat between Coccinella (0.96.4) and iChat (4.0)? (on both sides, a regular Jabber account is used and text chat is possible)
AFAIR iChat does not uses the Jingle protocol for voice chat and instead it uses its own closed protocol so that iChat is not interroperable with other XMPP software regarding voice chat. Also not that Coccinella uses IAX as transport method. If you want to be sure, you should ask the iChat people if they support the following 2 protocols and the Speex codec:http://www.xmpp.org/extensions/xep-0166.htmlhttp://www.xmpp.org/extensions/xep-0179.html
More information can be found here.
You can ask it for example in the iChat forum:http://discussions.apple.com/category.jspa?categoryID=139
