Move from BT, will the phone work

[Idonotknow]

Good morning, 

I'm thinking of joining Sky broadband with Sky talk included.
I am with BT and have just been upgraded to the digital home phones.
Will these phones work if I join Sky?

If your phone is designed specifically for use with BT's digital voice service, it won't work with Sky VOIP I'm afraid.

Thank you. 
I still have the old landline phones, so I assume those would work.

Yes, any standard phone, corded or cordless should be fine.
