Abstract
A system for cross-registration of a phone device is provided. The system includes a local call processing system that stores phone device information for a local phone that is operable to be used by a user; and a remote call processing system that stores a user phone profile for the user, the remote call processing system being operable to generate a visitor registration for the local phone device. The phone device is operable to use the visitor registration to register with the remote call processing system.
Claims19
A device comprising:
- a memory comprising:
- cross-registration instructions that are executable to cross-register a phone device located in a first call processing system with a second call processing system, the first call processing system comprising phone device information and the second call processing system comprising a user phone profile, wherein the cross-registration instructions are executable to generate a visitor registration in the second call processing system for the phone device and the visitor registration is used to login the phone device into the second call processing system;
- configuration instructions that are executable to initiate installation of the user phone profile from the second call processing system onto the phone device located in the first call processing system;
- and
- receive instructions that are executable to receive a phone call from the phone device;
- and
- a processor that is operable to execute the cross-registration instructions, the configuration instructions and the receive instructions.
A method comprising:
- receiving phone device information for a phone device located in a first call processing system, which does not include a user phone profile for a user of the phone device;
- determining whether a phone call made by the phone device is a flagged phone call;
- routing the phone call to the first call processing system when the phone call is flagged and to a second call processing system when the phone call is not flagged;
- generating a visitor registration for the phone device based on the phone device information;
- registering the phone device using the visitor registration;
- and
- transferring the user phone profile for the user from the second call processing system for receipt by the phone device located in the first call processing system.
A network device, comprising:
- a memory configured to store a plurality of local phone profiles;
- a processor configured to search the plurality of local phone profiles for a local phone device of a user, the processor further configured to generate a first registration in response to the local phone device matching one of the plurality of local phone profiles and to receive a second registration from a remote call processing system if the local phone device does not match any of the plurality of local phone profiles,
- wherein the processor is configured to use the second registration to login to the remote call processing system.
