Given that codecs appear in the end device and the 3GPP activity is to provide a gateway, either the gateway provides transcoding or the two end devices use SDP to agree on a mutually acceptable codec. 

Our view is that in many of these cases, it is perfectly possible for a webRTC device and the 3GPP device to decide to use H.264 as the codec and will do so, in order to avoid transcoding. 

That will occur whatever is specified as an MTI video codec.
