I believe most online directories get thier info from the local phone books so you will likely end up removed from these as well.Something also to remember is that you will more than likely lose all or some of your local phone book listings. We had that issue with a client they went VOIP and got removed from the local list, and white pages. The phone company said if you are not a paying customer you don’t get listed.
Granted most people here have a yellow pages ad, it can still cause a little issue.
