Hi all,

I am beginner to free switch.I have gone through the configuration file vars.xml in free switch.

In this I have seen the following configurations.

  <X-PRE-PROCESS cmd="set" data="internal_auth_calls=true"/>
  <X-PRE-PROCESS cmd="set" data="internal_sip_port=5070"/>
  <X-PRE-PROCESS cmd="set" data="internal_tls_port=5071"/>
  <X-PRE-PROCESS cmd="set" data="internal_ssl_enable=false"/>
  <X-PRE-PROCESS cmd="set" data="internal_ssl_dir=$${base_dir}/conf/ssl"/>

In the above I am having the doubt with tls_port. What is the use of tls_port .I have searched about this in net and I have read that tls protocol is used for secure data transfer in network.

So please explain me about the communication in freeswitch.

Thanks in advance.
