| 20090285204 | RECURSIVE QUERY FOR COMMUNICATIONS NETWORK DATA - An approach for providing telephony services over a data network is disclosed. A communications system includes a location server that receives a request from a calling station to establish a call with a station associated with a called party. The location server generates a message specifying a set of addresses relating to the called party and context information. A proxy server communicates with the location server and is configured to receive the message and to attempt to establish the call based on the set of addresses. The proxy server iteratively queries the location server to obtain another set of addresses if no prior address results in establishment of the call. | 11-19-2009 |
| 20090238177 | INTERNET PROTOCOL TELEPHONY VOICE/VIDEO MESSAGE DEPOSIT AND RETRIEVAL - A method for signaling an Integrated Messaging System (IMS) on an Internet Protocol (IP) based network to deposit a message, including the steps of sending a Session Initiation Protocol (SIP) SIP INVITE request to the IMS indicating a message deposit action; receiving a corresponding SIP message from the IMS agreeing to participate in the message deposit action; and sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and depositing the message in a destination mailbox. A method of signaling an IMS on an IP based network to retrieve a deposited message, the method including the steps of sending a SIP INVITE request to the IMS indicating a message retrieval action; receiving a corresponding SIP message from the IMS agreeing to participate in the message retrieval action; sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and retrieving the deposited message from a mailbox corresponding to known account information. | 09-24-2009 |
| 20090219925 | INTERNET PROTOCOL TELEPHONY VOICE/VIDEO MESSAGE DEPOSIT AND RETRIEVAL - A method for signaling an Integrated Messaging System (IMS) on an Internet Protocol (IP) based network to deposit a message, including the steps of sending a Session Initiation Protocol (SIP) SIP INVITE request to the IMS indicating a message deposit action; receiving a corresponding SIP menage from the IMS agreeing to participate in the message deposit action; and sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and depositing the message in a destination mailbox. A method of signaling an IMS on an IP based network to retrieve a deposited message, the method including the steps of sending a SIP INVITE request to the IMS indicating a message retrieval action; receiving a corresponding SIP message from the IMS agreeing to participate in the message retrieval action; sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and retrieving the deposited message from a mailbox corresponding to known account information. | 09-03-2009 |
| 20090110174 | CALLER TREATMENT IN A SIP NETWORK - In a SIP network, SIP servers are provisioned with information used to authenticate subscribers and entities that will be placing calls. This information can be used during call establishment to allow or deny calls, as well as to determine the appropriate party to bill if the call involves a charge, such as a long distance charge. In addition to allowing calls between authenticated and trusted entities, there is a need for the SIP server to allow certain kinds of calls that involve non-trusted users or entities. If non-trusted entities where not recognized, trusted users and entities within the SIP network would not be able to receive calls from users or entities not know to the SIP server that is providing them services. | 04-30-2009 |
| 20090097626 | SYSTEMS AND METHODS FOR IMPLEMENTING CALL PICKUP IN A SIP ENVIRONMENT - A method provides call pickup in a communications network. The method includes initiating a call from a first device to a second device. The call is initiated over one or more networks, where at least one of the one or more networks includes a data network. The method further includes storing information relating to the call initiation between the first device and the second device, receiving a message from a third device during the call initiation, where the message includes a call pickup indication, retrieving the information relating to the call initiation between the first device and the second device, and establishing a call between the first device and the third device based on the retrieved information. | 04-16-2009 |
| 20090082024 | METHOD AND SYSTEM FOR AUTOMATIC UPDATE OF A LOCATION PROFILE - An approach for establishing a communication session according to a subscriber profile that is automatically updated is disclosed. A locator device, which is associated with a subscriber and includes a Global Positioning System (GPS) transponder, outputs geographic information that is transmitted to a communications network for establishing the communication session. The geographic information corresponds to one of a plurality of addresses specified in the subscriber profile to set a current address. The addresses are associated with a plurality of devices adapted to complete the communication session. The one address is designated as the current address if the geographic information corresponds to the one address, otherwise the current address is set to a default address, wherein the communication session is established based on the current address. | 03-26-2009 |
