der output (4 bits in the first byte) ???=0A=A0=0ASo here is a scenario I would
like some feedback on:=0A=A0=0AClient A makes a narrowband Speex VOIP call to
Client B.=0A=A0=0AIn the SIP negotiation there is no information exchanged
besides the fact that it is a narrowband speex call (speex/8000)=0A=A0=0AClient
A operates at a bitrate of 11kbit/s (28 bytes per payload)=0A=A0=0AClient B
operates at a bitrate of 8kbit/s (20 bytes per payload)=0A=A0=0ASo client B
receives a payload of 28 bytes.=0A=A0=0AIs the application on B's side
supposed to extract the mode bits and reconfigure the speex decoder _before_ the
payload is=0Agiven to the decoder? I don't see how it would work unless the
decoder is reconfigured to operate at the same bitrate as=0Aclient A's
encoder???=0A=A0=0AAnd how is B guaranteed that A will also reconfigure its
decoder to operate at the same bitrate as B's encoder? Or should=0Athe
encoder on B's side _also_ be reconfigured to use the same bitrate as A is
using once the mode has been detected?=A0That =0Alooks like a cyclical problem
to me...so what am I missing here???=0A=A0=0AThank you.
