What's wrong with the Netgear router Going to use the SH3.0 for a day or two and monitor the VoIP for registration dropouts.This sounds like the best plan of action for now but as the superhub 3 doesn't support SIP ALG, I would expect issues when using it with VoIP. If your connection preforms well, your power levels look good, logs don't indicate any problems and you experience no packet loss when using the superhub 3 but you still have issues when using the Netgear router - Purchase a replacement VoIP friendly router (doesn't have to be expensive) from Amazon and give that a try! Although a hassle, you can easily return the new router if it doesn't preform well at no cost to you.
I'm fed up with it now. I need to get back to studying.
Remember: If you do re-connect your Netgear Nighthawk X4 R7000 router, factory reset it again and make sure that SIP ALG is disabled before re-connecting your Gigaset N300IP.
