You have to pay $40 to keep your old number when signing up for VOIP service through C*. I have verizon currently. Will the number transfer be immediate or do they assign me a temporary number until it is switched? I forgot to ask them and don't feel like sitting on the phone for 30 minutes since I'm at work and in meetings all day. So, if anyone knows I would appreciate it. I couldn't find that info on their web site. Thanks.
