I run small office which uses an older centos box that has asterisk installed. I painstakingly configured asterisk with the configuration files. Unfortunately, because the way our provider handles the internet handoff, I had to make the asterisk box the nat device for the office.
I would like to implement freepbx for a new iteration of the server, so I have decided to just deploy the FreePBX solution you folks provide
Upon installation, I noticed that it has an elaborate set of chains that are used.
Is it frowned upon to alter the iptables rules?
Additionaly, what about dhcpd? Can I configure it on the same box? Does FreePBX support provisioning of phones (Polycom 320)?
Thank you for your time.
