The Phones editor allows you to add (associate) and remove (disassociate) phone numbers from one service to another. You can re-assign Local Caller ID packages to a different inbound service by clicking Associate Service. You can also rotate these LCID (Local Caller Identifier) packages on different portfolios, keeping the Caller ID numbers fresh and callback rates higher. Disassociate Service button allows you to unassign a number from a service keeping the number within the client.

For more information on how to add (associate) / remove (disassociate) an inbound phone number to / from services, see the Phone Numbers Tab section of Services editor.
