Since you didn't mention what device/itsp is generating the incoming 
call, I'll have to assume you are trying to use sip with an external itsp.

If that's a correct assumption, the itsp may not support inband, 
suggesting the session is rfc2833 only.

You might want to try 'sip debug' and see what's happening, or 'set 
verbose xx' where xx is some large number like 30 or so. One or the 
other should provide more detail.
