Hi Evans1882,
Thanks for posting and welcome to our community 🙂
You wouldn't be able to just plug the phone into the hub, we would need to change some things from our side first.
If you do change over, you wouldn't be able to revert the line back.
It's not something we can do from here, but if you call us on 150/ 0345 454 1111 we can go through this with you.
