Setting Up VOIP

harbledown — Wed, 22 Oct 2025 15:35:48 GMT

Since going on Fibre 500 I've been using VOIP by connecting my analogue phones to the internet via Talktalk's adapter. I now have a Gigaset A300IP base plus Gigaset S700 handset which are both VOIP enabled. However, I can't get registered with Talktalk's service. I've logged into the Gigaset base but the settings Talktalk have given me (from the Online Chat) don't correspond with the info required by the Base for configuration. Has anyone any experience of this?

Have you connected the new base unit to your existing VoIP adapter?

You can also allow @ferguson to help, he's more skilled on these types of issues. Thanks for the support by the way @ferguson, it doesn't go unnoticed. Thanks

I did think that having a VOIP enabled base meant I didn't have to use the adapter. However I've connected the phone from Base to adapter and ethernet from adapter to Eero, but the handset shows "No LAN".

Hmm, not sure what you mean by VoIP "enabled," any handset should just plug and go. What are the lights on the Grandstream showing?

Three lights showing on the adapter. My analogue phone system is a Gigaset and when the Fibre 500 was installed the Gigaset base was simply plugged into the adapter and the adapter was connected to the Eero. I can't understand why I can't simply plug in the new A300IP base in the same way without having to configure it with a variety of settings.

Me neither. Have you tried reaching out to Gigaset directly? I have looked for that model on their website, but can't find it.

I've connected my old Gigaset base to the adapter as before but using the new Gigaset handsets (S700) and it works. So I'll have to leave it like that.

Since I last posted the system using my old base does not provide all the features listed on the handset. I still don't understand how I can plug in the old base with no configuration and VOIP works, but the n300ip base has to be configured.

@ferguson any suggestion on this?

Hi @nambuso-TT

Only to contact the phone makers directly, as I suggested earlier. It is not in any sense that I can see a TalkTalk issue.
