Hi Giovanni,
Although I'm not claiming to be an expert at all in isup-sip
interworking, the ITU Q.1912.5 document seems to say that it is not
necessary to encapsulate REL in CANCEL. You can take a look at the
example in Figure III.13/Q.1912.5 from Appendix III section of the document.

Hi Giovanni,
The CANCEL is hop-by-hop, which means each SIP hop will generate a
completely new CANCEL (to be sent further) - there is not
proxying, so the changes you do over the incoming CANCEL will not
propagate into the outgoing CANCEL.
Ciao Bogdan,
yep, saw that
I cannot recall it, but is there a standard case of pushing ISUP
into CANCEL ?
Not sure at all, I am looking around in various (too much)
documentation around the intertube, not yet sure if you must put isup
REL into CANCEL or not...
Have a nice wend!
