A plurality of communication devices are coupled to a communications network. Each communication device has a device identifier. A user-programmable database associates each of a plurality of user identifiers with a device identifier. A call-routing switch arrangement is coupled to the communication network through a portal communication device having a portal identifier. A user designates a destination user identifier when making a communication. The call-routing switches the call, directing the call to a destination device identifier responsive to the user-programmable database association between the destination user identifier and a device identifier. According to certain aspects, communications are directed to users and are routed to associated equipment, a user identifier serving as a virtual extension number. Users remotely program the database to direct their calls to communication devices at various geographic, voice mail and e-mail destinations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual telephone extension","description":"The present disclosure is directed to a method and system for routing communications.
