Hi George, Have you found a solution? I get same error: Q.850;cause=95;text="Invalid unknown header: Cannot add a parameter known to SipUri as a generic parameter" coming in reply from Teams when I send INVITE. I compared kamailio sent INVITE to one sent by a commercial SBC (working one) and I cannot find any difference. So I really not understand what header is not compliant to Teams. __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions -- [email protected] To unsubscribe send an email to [email protected] Important: keep the mailing list in the recipients, do not reply only to the sender!
