I'm new on RingCentral. My company is currently building a CC solution on RingCentral. I created a free account using my business email address and created a free sandbox using this account for proven of concept work. I can see RingCentral auto assign an ext "101" to it but no phone associated with it. So I went to phone system to add a Ringcentral soft phone to it. Then I tried to log into the softphone on my desktop using my email address but it failed saying "Sorry, you currently don't have permission to access this service. Contact your administrator to change permissions. ". What I need to do for me to successfully log into the softphone?
