I’m currently looking to replace the copper landline in a holiday house with a basic ATA on 2Talk or similar. I have an SPA112 at home which works well, but see that the unit is now EOL and is out of stock in many places. Any recommendation for a current equivalent? The most similar unit I’ve been able to find is the Grandstream HT801. The main requirement is reliability, and there isn’t any need for anything other than basic features.

The house has an Internet connection via a WISP.
