Hi Ben,<br>
<br>
Let me check what the history behind the lack of on_reply for the
CANCEL transaction, if it a simple miss or if there some good
reasons (mainly related to SIP consistency) not to have it.<br>
<br>
Regards,<br>

implemented some more detailed statistics capturing for our

that we track all transactions through the system.
Implementing this with dialogs was very straightforward,

<p class="MsoNormal"><span style="font-size:11.0pt">In the
meantime, I have created routes to track the transactions
but I am running into an issue with the CANCEL transaction.
It appears that the replies to a CANCEL will only ever
trigger the global onreply_route. When I arm a different
transaction reply route using t_on_reply it is never called.
Since the transaction is not available in the global reply
route, I cannot use it for my purposes.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Is it
intentional/expected that t_on_reply cannot be used with a
CANCEL transaction? If so, are there other methods that also
do not work?<o:p></o:p></span></p>
