It seems though there is no implementation yet that supports it. Btw. If anybody is interested I implemented such a SIP game for my thesis using mainly pjsua and mixing on client side. For the data exchange i used SIP SIMPLE, speaking of marshalling Game states into the MESSAGE Type. It works quite nice, with a openser registrar and allows you to easily equip existing games a ingame voice possibility. If anybody is interested in sharing some thoughts about it just drop me a line. 2008/4/28 Joegen E.
