Working from home during this current lockdown, my wife's work setup - consisting of a desk phone and desktop PC connected via a LAN cable - she is finding that 1 call in 4 has very poor voice quality over VOIP. It sounds like a cell phone cutting in and out, with choppy/poor voice quality.

Last lockdown I had my trusty old Netcomm NF4V, but this time around I'm using the Spark Smart modem. Her internet on her setup is okay, and everyone else can watch videos, plus my WFH setup is fine as well. It's just the odd phone call that is giving her grief.

Is there any setting I could be checking to ensure VOIP traffic is setup/prioritised correctly, etc?

I'm confused - Spark don't offer a RGW based VoIP service using the Smart Modem.

Sorry - it's a fibre connection, 100/20 with Spark, and she's connected to the Spark router via a network cable.

From there it goes into a TP Link "PoE Injector", and a network cable on the other side connects to her desk phone. After that, a network cable from the phone connects to her desktop machine.

Hopefully that isn't too confusing? It's an odd setup (to me).

Do you by chance know who the VoIP provider is?

Next you'll be telling us the brand of phone and VoIP provider.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.
