Here's few options and flavor that you can work with to silent the ring using CME.
SilentRing(s)You can configuresilentring on any type of phone.However, you typicallyset silentring only on buttonsofa phonewith multiplelines,such as a CiscoUnifiedIP Phone7940,CiscoUnifiedIP Phones7960 and 7960G,or a CiscoUnifiedIP Phone7914 ExpansionModule.The only visiblecue is a flashing((< icon in the phonedisplay.If you configurea buttonto have a silentring, you will not hear a call-waitingbeep or call-waitingringregardlessof whetherthe ephone-dnassociatedwith the buttonis configuredto generatea call-waitingbeepor call-waitingring.In CiscoIOS Release12.4(4)XCand later releases,the silentringingbehavioris overriddenduringactivenight-serviceperiods.Silentringingdoes not applyduringdesignatednight-serviceperiodswhentheskeywordis used.
MonitorMode(m)A line buttonset in monitormodeon one phonedisplaysvisualline statusfor a line that also appearsonanotherphone.Whenmonitormodeis set for a buttonwith a sharedline, the line statusindicatesthat thesharedline is eitheridle or in use. The line and line buttonare availablein monitormodefor visualstatusonly. Callscannotbe madeor receivedusinga line buttonthat has been set in monitormode.Incomingcallson a line buttonthat is in monitormodedo not ring and do not displaycallerID or call-waitingcallerID.Monitormodeis intendedfor use only in the contextof sharedlines so that a receptionistcan visuallymonitorthe in-usestatusof severalusers’phoneextensions(for example,as a busy-lampfield).To monitorall lineson an individualphoneso that a receptionistcan visuallymonitorthe in-usestatusof that phone,see the WatchMode(w) section.The line buttonfor a monitoredline can also be used as a direct-station-selectfor a call transferwhenthemonitoredline is in an idle state.In this case, the receptionistwho transfersa call from a normalline can pressthe Transferbuttonand then pressthe line buttonof the monitoredline, causingthe call to be transferredtothe phonenumberof the monitoredline.
Feature Ring(f)A featurering is a third type of ring cadence,in additionto the internalcall and externalcall ring cadences.For example,an internalcall in the UnitedStatesrings for 2 secondson and 4 secondsoff (single-pulsering),and an externalcall rings for 0.4 secondson, 0.2 secondsoff, 0.4 secondson, and 0.2 secondsoff (double-pulsering).A featurering is a triple-pulsering. The purposeof associatinga featurering with a line buttonis to beable to identifyfrom a distancea specialline that is ringingon a multilinephone.

Silentringing does not applyduring designated night-service periods when thes keywordis used.
Hope that help!
