Hello everyone,

In using FS for various scenarios I've noticed some behavior that
I'm not sure is completely "proper". Given that this probably lives
in mod_sofia who knows what's really "proper". It is SIP after all...

So the issue comes up when using FreeSWITCH as a B2BUA and bridging
between endpoints (very common). Should FreeSWITCH copy the X-
headers (possibly others) as it does now? I'd like to think it
shouldn't by default and the behavior should be one of:

1) Don't pass X-* (or anything else, really) from one leg to another.
If you want to pass specific X- headers (or anything else), set them
explicitly on the outbound leg.
2) Make the behavior configurable with a channel variable and/or
sofia config option:

{sip_pass_headers=all|none|X-MyCustomHeaderByName}

Thoughts?

There is this endless push and pull on this topic, those who want them
assume it should be default, those who don't assume that should be
default. This probably needs a configuration option defaulting to
pass them (those who don't want to pass them are usually a bit more
educated and would find the option better than the other way around).

Mike,

Thanks for getting back to me. I agree.

I'm willing to throw down on a bounty for this. Any idea how much
work we're talking about here?

Well since we aren't a proxy you shouldn't default to passing them
right?

Brian,

You are correct, they *probably* shouldn't be passed by default.
