We have a Cisco SPA525G phone connected with RingCentral. Contacts have been added to both ringCentral and the Cisco address book. If we receive a missed call, we receive a email informing us on who called. This only shows the number of the person and not the name. Is it possible for us to have it showing the name of the caller if we have them in our address book?
Kind of a Yes, you'll need to subscribe to a Ring Central plan that includes "Inbound caller ID name". Both notifications, via email and SMS, of a missed call will never "sync" with your personal contacts. Rather, they will display only the LEC provided Caller ID number (under the Standard Plan) and the LEC provided CLID and CNAM (under the Premium and Enterprise Plans).
