Hi, I have a few questions/remarks about the draft, in particular about the SDP usage of Speex (section 5): - Which samplerate should be used if you receive something like m=3Daudio 8008 RTP/AVP 97 a=3Drtpmap:97 speex/8000 a=3Dfmtp:97 sr=3D16000;ebw=3Dultra - There is an inconsistency in the description of the 'penh'parameter. According to the description, only the values '0' or '1' are valid. In section 6.1 however, the default values are defined as: ebw=3Dnarrow;mode=3;vbr=off;cng=off;ptime=20;sr=8000;penh=no; I assume that 'yes'/'no' are the valid values of the penh parameter, since these values are used in the other parameters. Is this correct?

What whould happen is that 8000 Hz would be used, but with a mode (ultra-wideband) that is not suitable for encoding that. The frame size would be 80 ms and the quality would be poor.> - There is an inconsistency in the description of the 'penh'parameter. > According to the description, only the values '0' or '1' are valid. > In section 6.1 however, the default values are defined as: > ebw=3Dnarrow;mode=3;vbr=off;cng=off;ptime=20;sr=8000;penh=no; > I assume that 'yes'/'no' are the valid values of the penh parameter, > since these values are used in the other parameters. Is this correct?Guess we need check that. I'm actually thinking of completely removing the penh field.
