I've often seen here that the same number can be identified from both the existing and new lines, but only incoming calling is affected.

In order to minimize confusion, most of the CLECs here will give their new lines completely new numbers in some stupid unheard-of area code so that we can identify them during the transition and put the jumpers in their correct places.

They have their porting assignments in their switch set to forward the existing numbers to the new ones immediately upon completion of porting.

After this occurs, they remove the forwarding when they receive confirmation that they have possession of the physical numbers. They then eliminate the stupid numbers and replace them with the real ones.

Man, that makes things SO much more pleasant. Then again, I am only speaking of the CLECs that we work with here. I'm sure that things vary in different territories.
