Hi @Jennyr231
If all you want is more Ethernet ports then buy a small Gigabit data switch with enough ports on it, such as this example:-
https://www.amazon.co.uk/TP-Link-LS1005G-Wallmount-Ethernet-Splitter/dp/B07VWB347G/ref=sr_1_3?crid=2...
Then connect the spare Ethernet port to the switch and all other Ethernet devices (including the Grandstream DVA if you have one) to the spare ports on the switch.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here How to contact TalkTalk Broadband - TalkTalk Help & Support
