<div class="moz-cite-prefix"><tt>Hi Mickael,<br>
<br>
If you do the "drop" in branch route, that branch will be
discarded (not sent out at all). IF no branch is actually sent
out, you will get the error logs from "t_forward_nonack" (as you
have).<br>
<br>
In this case, the t_relay() will fail (nothing sent) - to get
that error in script, set flag 0x02
(<a class="moz-txt-link-freetext" href="http://www.opensips.org/html/docs/modules/1.11.x/tm.html#id294578">http://www.opensips.org/html/docs/modules/1.11.x/tm.html#id294578</a>),
otherwise the error will be internally handled.<br>
<br>
A failure on sending does not trigger a failure route - failure
route is triggered only if request sent out and the transaction
completed with a negative code.<br>
<br>

<div>What happens after drop() is called from a branch_route?</div>
<div><br>
</div>
<div>In my case, I armed a failure route for the incoming INVITE
in the request route and therefore, I would expect that the
failure route would be called after drop() is called. However,
I see the following error in the logs and the following reply
is returned to the UAC.</div>

<div>I use the failure route to detect current transaction
failure and try the next termination if there is.</div>
