Currently the only way to import contacts is through a smartphone app that requires at least Android 5.0. My phone is at 4.4 and I’m not going to by a new phone so I can import my contacts.
You have an option to export contacts in CSV format to a PC file. So why do you not have an option to import contacts in CSV format?
I use Outlook and Gmail and both have an option to export in CSV format. I want to be able to import those files to my OOMA.
