when i was using maxis fiber a few years back, i configured the phone on the ONT itself
https://forum.lowyat.net/index.php?showtopi...60&p=91845910&#
power off ONT, unplug fiber cable(important), configure PC's IP address, power on ONT, login and configure

else, you might want to configure something like this:
ont -> pnic1 -> proxmox vmbr0 -> opnsense vnic1 (wan), vnic2 (voip)

pnic2 -> proxmox vmbr1 -> opnsense vnic3 (voip)

bridge vnic2+vnic3

pnic2 -> maxis router -> dect phone


edit:
or you can also try to bridge the 2 pnic interfaces in proxmox instead of doing it in opnsense

Hi Trix, thanks for the response. Do all these steps require messing with the ONT? I would prefer one that sets it up in OPNSense so the VM can be migrated to a different host in the future if needed without much issue. That link doesn't lead to anyone talking about VOIP? Am I missing something? I'm not opposed to having the maxis router in the loop although obviously not having it around is 1 less device to power and cable manage.

From what I can gather, "pnic2 -> proxmox vmbr1 -> opnsense vnic3 (voip)" seems like the easiest way to achieve that? I do have 1 extra port on my router/mini PC that I can use for the DECT phone/maxis router.

you only need to mess with ONT if you want to try the configure VOIP in ONT step
try this link, post #4186
https://forum.lowyat.net/topic/3487634/+4180#

btw, these are separate methods:
1.
ont -> pnic1 -> proxmox vmbr0 -> opnsense vnic1 (wan), vnic2 (voip)
pnic2 -> proxmox vmbr1 -> opnsense vnic3 (voip)
bridge vnic2+vnic3 in opnsense
pnic2 -> maxis router -> dect phone


2.
bridge the 2 pnic interfaces in proxmox instead of doing it in opnsense


if you will be using maxis router for VOIP, then doesn't matter #1 or #2
if you will be using any other software VOIP phone, need to use #1 with additional vlan tagging for voip in opnsense

This seems to be the easiest to implement, thank you!
