Does Freeswitch 200 OK message, which response to Invite, support "Authentication-Info"?

Hi All,

Here is a question, checked one log, 200 OK response to INVITE message, includes “Authentication-Info”. Likes as following:

SIP/2.0 200 OK
Via: SIP/2.0/TCP;branch=z9hG4bK2CEFE14B0016d07401a8c0;received=;rport=63649

The log in details is also attached.

Does Freeswitch support such function? How to configure Freeswitch to response 200 OK with “Authentication-Info”?

Hello @sparklezou,
Thanks for your question. I have never seen this behavior before. To my knowledge FreeSwitch cannot be configured to provide a 200 OK response with an Authentication-Info header. Perhaps you can provide some additional information of what you are attempting to accomplish, or why this is needed?

try to set sip_rh_Authentication-Info before answer
