both 2833 and actual tones in the audio stream are often called in-band because the 2833 is just a transport for the inband tones that is assumed to be reconstructed on the other side.  Some people refer to inband as the real tones and 2833 as not inband because it&#39;s not the tones.  So the one you have to look out for is people who call 2833 inband and do not clarify that it&#39;s inband packetized according the RFC2833 <div>
<br></div><div>The one that is not inband for sure is INFO (which has been dropped from the standard in favor of some ridiculous SUBSCRIBE based xml exchange) <br><br><div>Like all things in SIP and anything else that comes with an RFC even if you know the answer you can&#39;t rely on trusting that answer because the real world will do whatever it wants and invalidate you. =D</div>
