Sky Broadband and Phone Line

Hi, Im currently with Be for my internet but im thinking of moving to sky. I want to get my phone service from sky (pay them �10 line rental instead of BT) and get the 16mb package.
As i am moving my line to them would i still need my mac from be? Also how long would the whole process, switching line and getting bb up and running take?

Thanks.

The MAC has nothing to do with your phone service, so yes, you will still need one. Because your ADSL will be going from one LLU provider to another, it's possible that the changeover could take longer, but I can't say for certain.
