Hi Brett, as you probably already found out, you cannot (as proxy) say what codec is used in a call. You (as a proxy) see just the offerings (what codecs are available on each side) - after that, each side is free to select and use one of the offered codecs - so, only inspecting the RTP stream will provide you with the information regarding the used codec.
