Hallo Serge,
Fraunhofer IIS does have an MPEG-4 Phone implementation using SIP signalling to 
set up the call. In our case we have used a direct implementation (without 
DMIF), with the SDP and RTP packaging based on the ISMA specification. But you 
could probably also realize SIP as a DMIF filter.
Actually this is an interesting question to others on this reflector: Has 
anybody implemented a symmetrical protocol like SIP as a DMIF filter?
Best regards,
Bernhard Grill
