A method, apparatus and system for call leg selection is provided. In an embodiment, a call manger is provided which is connected to telephones that have the same telephone number. When the call manager receives an incoming call identifying that telephone number, the call manager sends a query to each of the telephones inquiring as to which telephone should receive the call. Depending on the response, the call manager will route the call to the appropriate one of the telephones.

Method, apparatus and system for call leg selection

A method of communicating information describing a voice call from a caller device to a recipient device. Call subject information describing the call is obtained from the caller device and sent to the recipient device to inform the recipient about the subject of the call. The call subject information is can be presented as a subject line displayed to on the recipient device to inform the recipient about the nature of the call and/or its urgency, thereby enabling the recipient to better determined whether to answer the call. The call subject information can be input by the caller or extracted automatically from an application from which the call was initiated.

Method and system for communicating and displaying data with a voice call

Communication devices capable of at least two communication modes (e.g. WLAN, WMAN and WWAN and/or wired modes) can be configured to optimize communications using a policy-based mechanism to configure connections and routes. A rules engine evaluates its policies on a state change (e.g. network availability, time of day, etc.) to configure a routing table and, together with communication APIs, provides an appropriate connection to an application for its respective communications. Policies may be responsive to various factors such as Radio Access Technology (high/low bandwidth), cost, presence, time of day, location, application type and quality of service (QoS) requirements among others to optimize communications.

Policy-based data routing for a multi-mode device

In one embodiment, an IMS network node is operable, responsive to receiving a SIP INVITE request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a SIP INVITE message back to the enterprise user. The IMS network node includes functionality for establishing a second call leg to the called party. The first and second call legs are patched to establish an end-to-end communications path between the enterprise user and the called party, wherein an enterprise address instead of a non-enterprise address of the enterprise user is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.

System and method for integrating an outgoing cellular call as an enterprise call in an IMS environment

The present specification provides an managing a document using printer emulation.

System and method for document transmission from a computing device to a portable electronic device

A method of managing communications services begins with a communications platform receiving a request for a communications service to be provided to a communications device by a source other than the communications platform. The communications platform determines an authorization of the communications device to receive the communications service. The authorization comprises a permission of the communications device to receive the communications service during a lifetime of a communications session maintained with the communications device. The communications network authorizes delivery of the communications service to the communications device during the lifetime of the communications session, in accordance with the authorization.

Communications services management using services profile

A method for discovering a communication device is disclosed. The method includes: receiving in the communication device a communication including a request for an address and an identification of an application, in response to receiving the communication, associating a dynamic address of the communication device with the identified application, and sending a second communication directly or indirectly to a client device, the second communication including the dynamic address. The communication device may further obtain a dynamic address in response to receiving the communication. The dynamic address may be used for a dedicated purpose, such as for receiving a file for subsequent use by the application.

Methods, systems, and mobile devices for managing mobile calls to or from an enterprise-associated mobile device. The system and mobile device are configured to ensure all calls over a public land mobile network are routed through an enterprise communications system. The mobile device is prevented from directly calling remote parties through the public land mobile network and the public land mobile network forwards all calls addressed to the mobile device to the enterprise communications system. The enterprise communication system responds to a request to connect the mobile device and the remote party by establishing a first call with the mobile device, establishing a second call with the remote party, and bridging the two calls to connect the mobile device to the remote party.

Method and system for managing enterprise-related mobile calls

An apparatus, and an associated method, permits a user to select a VoIP, or other packet-communication, service provider to be used pursuant to VoIP, or other packet-communication, services. Selection is made at a wireless device. The selection is communicated to a network entity, and the network entity integrates operations such that subsequent services are provided by way of the selected service provider.

Apparatus, and associated method, by which to select packet communication service provider at electronic device

A system and method are provided that enable a registrar or other server or proxy device to be used to provide a path between a pair of endpoint devices for exchanging addressing information, in order to establish a direct P2P connection. Once that connection is established, the connection may be used for any P2P data communications, e.g. SIP establishment of a VoIP call, instant messaging, online gaming, file transfer, multimedia streaming, etc. In this way, each endpoint device possesses a list of candidate addresses to establish a direct P2P connection, which may then be used for any type of communication. By relying on a registrar or other server to enable the candidate lists to be exchanged, control can still be maintained if necessary, since the candidate lists can be modified, e.g. to enable a transparent interception, to impose or remove security restrictions, etc.

System and method for enabling a peer-to-peer (P2P) connection

Exemplary methods and systems relate to telepresence at mobile devices. In one example the method can be performed on the mobile device. The mobile device can determine real-time availability of resources. The mobile device can further determine the composition of the telepresence session. The mobile device can further communicate the determined composition of telepresence data to a remote server. The mobile device can further receive telepresence data and perform a portion of the telepresence session data. Additionally, the present system can be configured to operate on a server or other electronic device.

Methods and systems for mobile telepresence

Aspects relate to call control by third parties, where IP or a similar transport is used over a part of the channel for a given call and circuit-switched signaling protocols are used on a different part. For example, a PBX can communicate using SIP signaling to a gateway to a PSTN network, to which a Public Land Mobile Network (PLMN) is coupled, and which a mobile device, uses for voice communication. Controlling or updating status in these kinds of situations can be accomplished by forming a Q.931/932 message, such as a FACILITY message, which has fields (Information Elements) for pre-defined purposes (other than third party call control), and providing control or status information in such field(s). The message (the info) is tunneled through the gateway and the network(s), and arrives at its destination device. That device determines that a field does not comport with a valid format interpretation, and on that basis, can determine that the field has contents to be interpreted as call control or status information.

Third party call control and status signaling

The present disclosure provides methods and apparatus for managing a document. An example aspect provides a method of requesting a document to be displayed at a portable electronic device, including: installing at a computer a printer driver for displaying documents at the portable electronic device; creating an association of a portable account identifier with a unique identifier of the portable electronic device; using the printer driver and the association, to transmit the document to the portable electronic device over a network; and transmitting from the computer the document.
