Hi GillianR1,
Thanks for your post and welcome to the Community Forums!
I'm sorry to hear you did not receive an adapter for your home phone to connect to your hub.
Sadly these adapters aren't something we supply or can send out to customers. However they are called RJ11 adapters and can be purchased inexpensively online or from most hardware stores 🙂
Hope that helps! Let me know if you need anything else
Beth
