Hi Jean-Marc and list,

I'm trying to negotiate speex with SIP/SDP and get some trouble
understanding the "mode" parameter:

mode:  Speex encoding mode.  Can be {1,2,3,4,5,6,any} defaults to
       3 in narrowband, 6 in wide and ultra-wide.

Is mode equivalent to the "quality" parameter of speex?

In this case, I don't understand why mode is not from 1 to 10...

Just for additionnal note, it seems the word "mode" is also
used for talking about the *-band things:
   "Each frame contains both "mode" (narrowband, wideband or

that's an additionnal confusion that may need a fix...

Thanks for all,
