Recently I purchased TP-Link VX800v G.Fast router from Elisa. The internet connection is working fine. Now I want to enter my VoIP (SIP) account settings but the “Telephony” tab on the router’s web interface is missing.
I found on the internet that it should look like this

but no such tab can be found on my router.
This is what my router’s web interface looks like, “Telephony” tab is missing.

The router itself has 2 phone ports and DECT support. And VoIP features are advertised on the shop’s page.
Laadukas puhelinliitäntä: VoIP ja DECT - yhdistä jopa 6 langatonta luuria ja 2 analogista puhelinta.
VoIP-ominaisuudet: 8 SIP-tiliä, soitonsiirto, puheluestot, vastaajatoiminnot.
I am confused. Can it be that Elisa intentionally disabled this feature on their firmware?
