I have an awkward Tekelec that ignores Record-Route and insists on
talking directly to UAs, making it very difficult (impossible) to detect
hangups - BYE is sent directly to the UA, bypassing YXA.
However, if I force Contact to point to Yxa, the BYE messages come to
the proxy server as required.
The problem is that this is quickly turning into a ugly hack and I was
wondering, before going further, if there was a better way. Perhaps
someone else has faced and resolved this issue before?
