I set up a customer link for primary telecom number and have started the port process to 2talk.
My land line now has a new number(number swap).
I will be moving to NDSL with the same BB provider(slingshot).

So this way if the port happens first my land line with BB still works(as it has a different number).
Or if the the naked connection happens first then my primary number is safe as its customer linked.

Does this sound correct guys?
