<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>

the problem is that the device you interconnect with (Server: sbc_5) is not sending all the Via headers from INVITE in the 487 -- it is only one Via:<br>

<br>
<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>
<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<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>
<br>
Cheers,<br>
