But by the time you have all that information, it's too late (at least for OpenSIPS) to do anything about it. It'd have to be dealt within MediaProxy. > It's the simplest way I found to be able to decide to use transcoding or not > on the fly. What do you think of this approach ?

And also, the SDP must be fixed, because endpoints will need to know in what codec they are talking. This last thing could be faked by always adding G729 to the offer and answer, but I've seen some devices fail if they get more than one codec as an answer.
