Automaticaly sync Contacts from Ringcentral Apps and Phone to High Volume SMS website

Currently, High Volume SMS does not have any contact from RingCentral. Please improve the integration from High Volume SMS with RingCentral Apps and allow Ringcentral Phone App to have the same access of send Text Message with the same number that being used on High Volume SMS. It is very inconvenient to have using 2 different platform in order to manage the voice calls and messages.
