| Article Number: 66 | Rating: Unrated | Last Updated: Wed, Sep 22, 2010 at 1:17 PM |
Getting StartedIf your Asterisk PBX is behind a NAT firewall, i.e. the PBX has an IP such as 192.168.0.2 then you will need to perform additional configuration to allow Asterisk to route the SIP and RTP correctly. Basic ConfigurationThe NAT configuration can be found in the file /etc/asterisk/sip.conf, the relevant section that needs to be edited is reproduced below: Once the file has been edited, you will need to restart Asterisk, consult your distribution documentation on how to perform this, for example: service restart asterisk sudo /etc/init.d/asterisk restart Advanced ConfigurationA further consideration is that you should ensure that you have configured port forwarding correctly on your router due to the PBX being in a NAT environment |
