Hello,
i already installed FreePBX and i have 3 NIC, if using freepbx 13 all NIC can be used. but if using freepbx 14 only 1 NIC can be used.
I found this thread “fpbx-14-bypasses-network-input-screen-at-installation”
I doubt it. You might be able to crawl around in some repos to import the kernel drivers and recompile them, but when a 1gbit network card is literally $4 delivered, I can’t see why anyone would bother 8)
Almost all of the small servers I field come with and use Integrated NICs. Not all motherboards support 1G onboard network connections. Having to add another card to the machine adds trouble when building the system and can mess with the “rocket scientist” that installs my systems. He’s family, though, so I have to make things “Gary-proof” as much as possible.
