I suspect the answer is a big NO, but....

Have ordered UFB - it will be naked fibre
Would like to keep the old landline number for a while - so figured 2talk will be ok for that.
Dont have a router that has POST/VOIP ports built in - so figured I need an ATA.

But I see the Chorus ONT has POTS ports on it - Vodafone and Spark can use/activate them - so they must push something out to those ports somehow? Slingshot/Orcon supply a router with POTS/VOIP ports and their customers have to use that.

So the question is - is it possible to have the chorus ONT POTS ports working with 2talk?
