Is there anything special that needs to be done to get Freeswitch/Sofia to support RFC 5626 for inbound registrations? I have a PJSIP client sending "Supports: outbound" with a reg-id and sip instance, but FS doesn't respond with Require: outbound and so PJSIP appears to think SIP outbound isn't enabled.

I see the Sofia param rfc-5626, but that only seems to affect outbound registrations to upstream SIP providers that FS is registering with when acting as a UAC.

Best,

Colin
