title: What ports does freeswitch need open?
body: <p>I have installed FreeSWITCH 1.0.6 on CentOS 5.5.  I believe CentOS is blocking the ports FreeSWITCH needs in order to contact with my remote phones, but I have no idea how to use ipTables in Linux or what ports need to be open.  Can anyone help?</p>
  
  <p>With Asterisk the ports were 5060 - 5090 for sip and a few others but I don't remember them.</p>
  
  <p>Thank you!</p>
