Hi there, What do you think I am doing wrong when my connection to Freeswitch over TLS from Bria softphone ends with: "could not be enabled. Problem at server (SIP error 503)" Configuration: Server: CentOS 5, Freeswitch 1.0.6 (fresh installation from a tarball) Client: (K)Ubuntu 10.04, Bria 3.1 -firewall is OK, telnet on port 5061 OK, iptables OK, tcpdump shows traffic -server CA certificate imported on client computer to system-wide keystore database (dpkg-reconfigure ca-certificates) -TLS enabled in vars.xml Also (with no TLS connection) - I can register phone (Bria, Empathy), I can dial to another user, hear ring tone, pickup the phone call - but I can not hear person on other side. I can just see that my microphone works. Thank you for help. Any advice appreciated. Cheers, Milan
