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? -- Kristian Kielhofner http://www.astlinux.org http://blog.krisk.org http://www.star2star.com http://www.submityoursip.com http://www.voalte.com
