[speex-dev] RTP Payload Format for the Speex Codec

[Tom Moers]

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?

Best regards,

Tom Moers
