I have a list of contacts set up on Ringcentral's website. From my phone (Polycom VVX310) I only have "no records" in my phone's contact directory (Home > Directories > 1. Contact Directory...). I have the ability to add contacts (one at a time manually using the phone buttons) but that is a daunting task. I want to know if it is possible to synchronize my Ringcentral contacts with my phone's contact directory. Alternately, is there a way to upload a contacts file to the phone so it has my list of contacts.
