Ring central app in Salesforce does not show users and queues like in Avaya phone app. When trying to transfer a call or look up a caller then only salesforce contacts come up and not Avaya contact names and groups. User has to manually look up internal colleagues extension number or call queue in Avaya app and copy that number into Ringcentral app within Salesforce and then transfer number. Adding and removing contacts within salesforce every time a user is joins or leaves the business is double work . It would be much simpler if the contact that is added to Avaya is also added to Ringcentral.
