This will be negotiated by FS and the carrier when the call is set up. For instance, when you use G729 you need out of band DTMF but for G711 you can use both. This might change from call you call, depending on what media gateways can handle.<br>
<br>If you want to "see" and hear DTMF - fire up wireshark (or Tshark) and capture the trace. You can see the RTP DTMF in the trace and hear the clamped audio from the carrier perhaps. Or just hear the inband tones. It gives a good visual of what is going on.<br>

confusion</div>
<div><br></div>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'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'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't rely on trusting that answer because the real
world will do whatever it wants and invalidate you. =D</div>
