I recently had my 30/10 VDSL2 connection upgraded to 30/30 CIR with Wireless Nation at our apartment in Auckland (Grafton Road between Grafton Bridge and SH1). I have run into a lot of VoIP call quality issues as of late and am trying to isolate the problem with so many factors at play:
Polycom VVX 410 IP Phone --(wired)-- INNBOX v50-u modem --(wired)-- Wireless Nation --(wired)-- pacific cable --(wired)-- voip.ms VOIP provider
Just looking for any thoughts in case someone else has ran into similar issues.
Here you can see there are regular packets being lost - at least at the ICMP level - when running PingPlotter from a wired connection to the INNBOX modem. The IP phone is also wired into the same modem. When I'm on a call it is typically my voice (upstream) that drops or becomes robotic - I have never had an issue hearing audio from the other end.
Here is what I'm seeing on the DSL side from the modem:
Is the INNBOX modem considered decent for the VDSL service in NZ or is there a better option? Any thoughts / advice?
