I don't know whether the Asterisk default codec is still ulaw or not, though I believe it is.
But it doesn't matter. Any connection in the same call between multiple legs which each use a different codec, whether GSM or otherwise, will of course require Asterisk to consume CPU in transcoding between the two different encodings. Each leg gets a codec which transcodes to Asterisk's native encoding (which I believe is ulaw), in which encoding mixing and other signal processing is performed, before reencoding back into the encoding each leg uses.
