Hi List, 

After some researches, I didn't have found how to remove the X-FS-Support of SIP INVITES sent by Freeswitch.

Example : X-FS-Support: update_display,send_info

I've tried modifying "ignore_display_updates" variable, as described here : http://wiki.freeswitch.org/wiki/Variable_ignore_display_updates, and modifying "pass_callee_id" variable (even if I doubt about it...) without any success.

Have you got any other idea ?
It's important for us to be able to suppress this header, because of our SIP provider SBC, which doesn't support it...

Thanks a lot,  

Bien cordialement, 
Best Regards, 

Kevin MATHY
