Well the techs arrived today and got the ONT working and let me set up the NF18ACV for fiber because they weren't familiar with that aspect.
Got that working but the VOIP setup alludes me. It seems I have to accept a replacement NF18 from Slingshot they say due security issues I cant set up the VOIP myself.
Ive tried as attached, using my slingshot login password.
It worries me a bit because I dont like having yet another modem (Ive already got 3 that work perfectly well) and 2 of them are VOIP eg NF14V & NF18ACV.
Also worries me that the wifi on their one might be rubbish as its likely to be using the older firmware which has proven hopeless here; there is an update for Netcomm NF18ACV which came out this September/2019 which makes the wifi work a heck of a lot better.
Is it really so difficult to get the settings out of Slingshot, or is each VOIP service fixed to a specific MAC/specific modem?
BTW Slingshot so far have been a superior ISP in their response and support efforts with my many difficulties with UltraFast Fiber.
