Decide if you want to have a separate phone number for work

Here is the link for Google Voice https://voice.google.com/u/0/about

One thing I forgot to mention is that if you want to switch from Google Voice to some other service at some time, you can always port your number to the new provider. Usually you will have to contact them and they will do the work for you. This is of course important because you do not want to change your phone number!
