Disclosed are a network-based device, method and computer readable medium for operating an IMS to provide IMS services to originating sessions from a device upon which the user is not registered. The method includes receiving communication from a user on a device upon which the user is not registered at a 2-stage dialing server, authenticating the user, determining a Public User ID (PUID) for the user, receiving an identification of a called party from the user, arranging for IMS services to be provided to the user on the device, sending an INVITE signal from the 2-stage dialing server on behalf of the user PUID to the called party and setting up the media connection from the device to the device associated with the called party.

System and method of providing IMS services to users on originating non IMS devices and other devices that do not have a previous relationship with the user

Disclosed is a device in an IP Multimedia Subsystem (IMS) that provides IMS services to terminating non-IP (TNIP) devices. The method includes receiving a message to register a Public User Identity (PUID) at a TNIP device at a network-based device, the TNIP device being at an E.164 routing address, establishing, in a network device accepting communications where to send sessions destined for a PUID and providing information where to send sessions, the routing address as a final destination of sessions to the PUID based on the registration and an IP address of a network device with routing functionality based on telephone numbers as immediate destinations and using information from the registration to route to the TNIP device, after providing IMS services, using the relationship between the PUID, the routing address and the IP address of the network device with routing functionality based on telephone numbers.

A packet switched telephone system includes a packet switched routing apparatus. The packet switched routing apparatus selectively associates a local telephone number with a phone call based on a called telephone number, and routes the phone call based on the called telephone number. The local telephone number may be substituted for a calling telephone number when the called telephone number corresponds to a predefined number, such as an emergency number. When the called telephone number corresponds to an emergency number, the phone call may be routed with the substituted local telephone number to a Public Safety Access Point (PSAP) that services the local area of the subscriber.

Methods, devices, and computer program products for providing ambient noise sensitive alerting. The methods comprise receiving ambient noise, converting the ambient noise to an electrical signal, detecting a parameter of the electrical signal which is indicative of ambient noise, sensing an incoming call or message, and controlling the volume of an audible alert in response to the detected parameter of the electrical signal.

Systems and methods are provided for using partially non-geographic addresses. One example method includes: determining whether addressing information in a received message comprises a scoped code; examining, upon determination of a scoped code, a non-geographic portion of the addressing information; obtaining forwarding information corresponding to the non-geographic portion of the addressing information; and forward the message in accordance with the forward information.

Communication system and method using partially non-geographic addressing method for forming same

A communications process and apparatus is provided with scoped, partially non-geographic addressing. The processes are carried out by one or more switches in a communications system. A first device in the system has a scoped address, including at least one geographic identifier and a customer identifier. A second device sends a setup message with addressing information to a switch in the system. The switch examines the message and consults a database with the customer identification to determine forwarding information. The switch forwards the message to a second device according to the forwarding information obtained from the database. The second device sends a connect message to the first device, thereby establishing a connection.

Communications systems and method using partically non-geographic addressing method for forming same

A system and method for routing communications to a terminating station associated with a porting subscriber directory number when the porting subscriber line 14a is cut-over from a donor switch 12a to a donee switch 12b. Upon cut-over of the porting subscriber line 14a, a local number portability (LNP) activation telephone call is placed to a dial-in platform 50 that activates a previously provisioned but inactive LNP database entry for the porting subscriber directory number. The LNP database entry is located in an LNP database 42a at a service control point (SCP) 28a. The dial-in platform 50 also activates a previously provisioned but inactive directory-number-level trigger for the porting subscriber directory number at the donor switch 12a. Activating the directory-number-level trigger for the porting subscriber directory number at the donor switch 12a causes the donor switch 12a to hold a subsequently received telephone call directed to the porting subscriber directory number. The donor switch 12a then transmits a query message to the SCP 28a and holds the telephone call until it receives a response message including routing instructions from the SCP 28a. Activating the LNP database entry for the porting subscriber directory number in the LNP database 42a at the SCP 28a associates the porting subscriber directory number with the donee switch 12b. Activating the LNP database entry therefore allows the SCP 28 to determine the correct terminating switch for the held telephone call, which after cut-over, is the donee switch 12b.
