I have my GrandCentral phone number set up and have looked around at the available features, and I must say that I’m impressed with all that it can do.  I haven’t started to distribute my number yet, but now that I know there will always be a free, basic, version of GrandCentral I think I will.  I have a work cell phone and personal cell phone that I constantly forward my calls back and forth to.  Getting rid of that hassle should make up for the hassle of giving out a new phone number.  Grand Central forwards Caller ID info to you which makes it easy on you, but it’s a little more problematic for the people you call, to show up correctly on thier caller ID they’ll still need to have all your phone numbers associated with you and you GC number on top of that.  It will be interesting to see if people will use the new number or just stick to what they have already pre-pregrammed.  The other big downsides are…that you can’t use phone extensions right now, which means I can’t use my office phone (cubical phone?).  I’m not sure I would want my personal calls coming in to that number anyway.  The last problem is a limitation on forwarding, each external phone number can only have one person forwarding to it, so if my wife uses the service only one of us can forward calls to our home phone.  I’ll have to start playing with the features tomorrow and I need to hunt down what features are considered to be the “premium” ones.
