Mi Ke, You should put your actual remote provider’s domain name or tip address in where it says “remote_ip_here” and I assume you have entered you actual username and password where it says “yyy” and “zzz”. It should look SIMILAR to this, but with your provider: <param name="realm" value="sip.voipinnovations.com:5061"/> Hope that helps, Sean From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Mi Ke Sent: Wednesday, June 20, 2012 11:46 AM To: Freeswitch Users Subject: [Freeswitch-users] gateway registration using TLS Hi All, Is it possible to explicitly tell sofia to register as a client using TLS?
