Firewall Configuration for Elastix

In order for Elastix to work with VoIP providers and directly connected external extensions it must be able to establish communication to the devices and VoIP provider. Additionally, the firewall must be prepared to operate correctly with SIP. A firewall without an integrated SIP server (such AVM Fritz box or Speedport) or SIP ALG is preferable.
