Hello, I enabled ssl in my FS installation. Here are few lines from my vars.xml: <!-- SIP and TLS settings. http://wiki.freeswitch.org/wiki/Tls --> <X-PRE-PROCESS cmd="set" data="sip_tls_version=tlsv1"/> <!-- Internal SIP Profile --> <X-PRE-PROCESS cmd="set" data="internal_auth_calls=true"/> <X-PRE-PROCESS cmd="set" data="internal_sip_port=5060"/> <X-PRE-PROCESS cmd="set" data="internal_tls_port=5061"/> <X-PRE-PROCESS cmd="set" data="*internal_ssl_enable=true*"/> <X-PRE-PROCESS cmd="set" data="internal_ssl_dir=$${base_dir}/conf/ssl"/> Then I restarted my server and found the following errors: 2010-11-10 20:22:37.555517 [ERR] sofia.c:1446 Error Creating SIP UA for profile: internal-ipv6 2010-11-10 20:22:37.576362 [ERR] sofia.c:1446 Error Creating SIP UA for profile: internal The "sofia status" command does not show the internal and internal-ipv6 profiles. This wiki page: http://wiki.freeswitch.org/wiki/SIP_TLS#If_your_SIP_profile_fails_to_start_u... talks about exactly this problem and it suggest that libssl-dev is not installed. But when I checked my Ubuntu 10.04 I found it to be installed. I also installed "libcurl4-openssl-dev" and then did "make; make clean; make install" and reran the server. However, the problem persists. Can anyone tell me what else may be wrong with my server? Thanks, Farhan
