Hello,<br>
<br>
the forward() doesn't take variables as parameter, you have to set
$ru or $du to the address where you want to send and then just use
forward().<br>
<br>
Also, rewrite*() functions do not work with variables.<br>
<br>
In assignments, inside the strings of expressions, the vars are not
evaluated, you need to use concatenation (+):<br>
<br>
$du = "sip:" + $var(cancel_dst) + ":5060;transport=udp";<br>
<br>
Cheers,<br>
Daniel<br>

My guess that the sbc_5 is so poor implemented that it takes
the Via from last request, which is CANCEL, but CANCEL is a
hop-by-hop request in this case. If my guess is confirmed,
the implementation of sbc_5 is really far away from RFC3261,
something that I haven't probably seen since 2002/3.<br>
<br>
To test, you can try to use forward() for CANCEL instead of
t_relay(). But you need to know where to send it -- same
address as for INVITE -- you can hardcode some values in
config for sake of simplicity to test. A proper workaround
can be built using htable module to store where the invite
was sent, using call-id as a key.<br>

what would be relevant here is seeing the INVITE
request sent to 10.14.0.1:5060 -- paste it to the
mailing list discussion. That is going to be used to
generate 487, and the Via stack from it should be
used there.<br>
