I have been migrating from the Orcon router to an EdgeRouter Lite but am having troubles getting the VOIP service working.
I have the following set up:
Chorus NTU -> EdgeRouter Lite -> Unmanaged Switch -> NF4V
This works! But when I remove the unmanaged switch and connect the NF4V directly into the ERL the VOIP status stays down.
The NF4V can still ping external addresses including voice.orcon.net.nz.
I just don't know what the unmanaged switch could be doing that's making a difference.
