Hi, I used the downlaoded TAR ball and my calls worked, however, when upgrading to the SVN release...my SBC is rejecting the 200 OK (when the FS answers the call - using Conferencing app).. Here are teh bad and good 200 OK,,,,I see a lot of additional headers startin gwith X:FS , can I remove them?

No you can't remove them... And they are 100% valid so your SBC is in the wrong. /b On Oct 26, 2009, at 12:05 AM, Ujjval Karihaloo wrote:

Brian, This bothers me a bit. Of course they are "valid". Anything prefixed with X- should be ignored by the remote end unless they are specifically looking for it. However: 1) We all know that just because the spec says they are valid doesn't make it so with every vendor. 2) As long as these headers are being attached people are going to keep coming to the list with issues because of them. 3) Attaching (seemingly arbitrary) headers like this breaks "interop agreements" that we (the users) have with carriers and other vendors. Every header we add is another reason why $CARRIER will refuse to support me because "my INVITE doesn't match what I had during interop testing". 4) Why do we /need/ these headers in the first place? What is using them? If we don't really, really, really need them they shouldn't be there. 5) Depending on the reason for them being there, this should still be configurable. I just don't see why not. Obviously we could always just patch the code (Sonus log statements :) but that probably shouldn't be necessary here. I'm not trying to be difficult; I'm just looking for a better explanation and real discussion. On Mon, Oct 26, 2009 at 10:35 AM, Brian West <brian@freeswitch.org> wrote:

The headers are used to pass the callee-id info back to the other side so you have the id of who you called. 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. =/ On Mon, Oct 26, 2009 at 10:15 AM, Kristian Kielhofner < kristian.kielhofner@gmail.com> wrote:

Anthony, So if I'm understanding you correctly, if you are always using FreeSWITCH as an edge to other systems you should be able to safely disable these headers? On Mon, Oct 26, 2009 at 11:41 AM, Anthony Minessale <anthony.minessale@gmail.com> wrote:

I agree with you, X headers should be ignored by the equipment normally. Anyhow Kristian has a point here; there will be a lot of complains because of broken SIP stack on many vendor equipments So, can you consider some customizable a config option for such headers? T.

Thus perpetuating the wild-west of sip where you can't do anything according to spec because you have to worry about stupid things not keeping up. Sounds like the education system where I live too..... I'll see what I can do. It's always the other end that ppl pay for that drive the free stuff to change its code.
