The headers are used to pass the callee-id info back to the other side so you have the id of who you called.<br>The standards have failed us in this case as everything does it differently to the point that there is no standard thus we have invented our own way to carry this across from one FreeSWITCH box to another, but of course we can never make anybody happy. =/<br>

This bothers me a bit.<br>
<br>
Of course they are "valid". Anything prefixed with X- should be<br>
ignored by the remote end unless they are specifically looking for it.<br>
<br>
However:<br>
<br>
1) We all know that just because the spec says they are valid doesn't<br>
make it so with every vendor.<br>
2) As long as these headers are being attached people are going to<br>
keep coming to the list with issues because of them.<br>
3) Attaching (seemingly arbitrary) headers like this breaks "interop<br>
agreements" that we (the users) have with carriers and other vendors.<br>
Every header we add is another reason why $CARRIER will refuse to<br>
support me because "my INVITE doesn't match what I had during interop<br>
testing".<br>
4) Why do we /need/ these headers in the first place? What is using<br>
them? If we don't really, really, really need them they shouldn't be<br>
there.<br>
5) Depending on the reason for them being there, this should still be<br>
configurable. I just don't see why not. Obviously we could always<br>
just patch the code (Sonus log statements :) but that probably<br>
shouldn't be necessary here.<br>
<br>
I'm not trying to be difficult; I'm just looking for a better<br>
explanation and real discussion.<br>
