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. 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.

Our customers use different equipment for sending traffic and I'm not sure what kind of equipment our carriers are using. So, I can't really tell what device they're using.
