<p>Multiple cellular telephones, each having a unique ESN, share the same cellular telephone number (MIN). Data records at the mobile switching center (MSC) are modified to reflect the parent and extension cellular telephones configuration. Incoming calls are delivered to all telephones sharing a MIN simultaneously, sequentially, or in accordance with a caller's selection. An extension wireless telephone may interrupt a call in progress of another extension wireless telephone. Cellular telephones sharing a MIN may call each other using intercom extension numbers. <IMAGE></p> |
