Just moved NBN & Voip from TPG to Spintel. Took the Archer VR1600v across.

did basic config for internet, so that's connected.

but,

TELEPHONY option is missing from TPLink login.

Can't configure modem/router for VOIP.

Called TPG who originally issued the modem. They categorically state that they did not alter/remove the TELEPHONY option.

How to fix this please?   Do I need to update the firmware?

Current firmwire on modem:  0.1.00.9.1v5006.0 Build 200810 Rel.53181n

Hardware version:      Archer VR1600v v2 00000000

Please help, I don't want to lose the landline.  And not very techno.

Thanks

(btw, Model type dropdown does not have mine, and won't let me proceed unless I picked one)
