<p>Hi Giovanni,</p>
<p>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.</p></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">Thanks a lot Vlad!</div><div dir="auto">I will sure look into It.</div><div dir="auto"><br></div><div dir="auto">Btw, SIP-I module rocks!</div><div dir="auto"><br></div><div dir="auto">-Giovanni</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div text="#000000" bgcolor="#FFFFFF">

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.<br>

I cannot recall it, but is there a standard case of
pushing ISUP into CANCEL ?<br>

<div>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...<br>
