I have found that I am not able to import my full google contacts onto my 2182. I have tried to add numbers into the phone book, but it is non-intuitive on add information, specifically names. For instance, I can't delete letters nor can I insert a space. I am not sure if this is covered in the manual since I can't seem to find a manual for the 2182, but I am sure that the question is appropriate for any of the Obi phones.
If you follow the "Documents" link on your Dashboard you will find the Admin Guide for Obiphones.
