In various embodiments, a device receives profile data regarding users or devices of an on-premise telephony system. The device identifies, based on the profile data, group features associated with the users or devices of the on-premise telephony system. The device forms a candidate set of users or devices of the on-premise telephony system for migration to a cloud-hosted call agent, based on them sharing at least one of the group features. The device provides data indictive of the candidate set of users or devices to a user interface for display.

Cloud migration utilities for telephony services

A Session Initiation Protocol enabled network connected device receives a client certificate from a client device. The SIP enabled network connected device validates the client certificate from information received from a certificate authority. The SIP enabled network connected device determines an identifier of the client device from the client certificate. The SIP enabled network connected stores the identifier of the client device. The SIP enabled network connected device receives a SIP message from the client device. The SIP enabled network connected device inserts the identifier of the client device into the SIP message. The SIP enabled network connected device transmits the SIP message to a destination SIP enabled device after inserting the identifier of the client device into the SIP message.

Certificate-based call identification and routing

First call identification information is stored at a network-connected device. The first call identification information identifies a call between an initiating device connected to an Internet Protocol (IP)-based network and a called device connected to the IP-based network. The call identified by the first call identification information is established through a telephone carrier network. Second call identification information is stored in the network-connected device. A determination is made that the first call identification information and the second call identification information identify the call from the initiating device to the called device. The call is connected through the IP-based network so as to avoid the telephone carrier network based upon the determining that the first call identification information and the second call identification information identify the call.

Internet protocol telephony with variable-length carrier systems

In one embodiment, a method includes obtaining geographic information from a first party when the first party attempts to join a collaborative session, and identifying a first geographic region, using the geographic information, within which the first party is located. A first multipoint control unit (MCU) located within the first geographic region is identified for use in a dial out to establish a first audio connection for use by at least the first party during the collaborative session. The method also includes establishing a voice over Internet Protocol (VoIP) connection configured to shunt video between the first party and a cloud during the collaborative session, and causing the first MCU to dial out to establish the first audio connection to the cloud. The first audio connection is configured to shunt audio between the first party and the cloud while the VoIP connection shunts the video between the first party and the cloud.

System for delivering unified conferences in light of prohibition of toll bypass

Messages sent from an initiating device to a called device to establish a telephonic communication session between the initiating device and the called device are received at a network device. One of a first network or a second network is selected to establish a first communication path of the telephonic communication session. The first network comprises an Internet Protocol network to which the initiating device and the called device are connected, and the second network comprises a public switched telephone network. Messages are sent to the called device via the one of the first network or the second network to establish the first communication path. A second communication path is established between the initiating device and the called device through another of the first network or the second network. At least a subset of data also being sent over the first communication path is sent via the second communication path.

Lawful intercept in an internet protocol-based telephony system

Techniques are described herein for facilitating a connection between a cloud networking platform and a unified communication system, where the cloud networking platform hosts communication services including real-time communications for client devices, and the unified communication system hosts communication services including real-time communications for on-prem devices that are associated with the unified communication system. Events associated with the cloud networking platform are monitored at the unified communication system, via a cloud connector device of the unified communication system, where events are associated with users who are registered with client devices and on-prem devices, and the events include real-time communications. A notification is provided to one or more client devices registered to a first user in response to an on-prem device also registered to the first user receiving a real-time communication request from a device of another user.

Enterprise integration with cloud-based multimedia system

Providing an announcement for a multiparty communication session involves establishing a communication session between at least two endpoints. A request to add an added endpoint to the communication session is received. A procedure to provide an announcement to the endpoints of the communication session is initiated. The announcement is played in response to determining a status of a media path of the added endpoint, and is provided from a rendering of a participant identifier associated with the added endpoint.

Providing an announcement for a multiparty communication session

In one embodiment, a method includes obtaining a potential bandwidth deduction at a call agent, the call agent being associated with an intercluster call admission control (CAC) arrangement in which bandwidth is shared, the potential bandwidth deduction being associated with a session. The method also includes determining whether the potential bandwidth deduction is a duplicate bandwidth deduction, deducting the potential bandwidth deduction from a bandwidth bucket when it is determined that the potential bandwidth deduction is not the duplicate bandwidth deduction, and ignoring the potential bandwidth deduction when it is determined that the potential bandwidth deduction is the duplicate bandwidth deduction.

Method and apparatus for supporting call admission control using graph assembly and fate-share identifiers

In one embodiment, a communication is established between two endpoints. The communication session may be a video call or an audio call. The communication session may be managed by a call manager using, for example, voice over internet protocol and session initiation protocol. One of the endpoints initiates recording the communication session. The call manager facilitates recording the communication session based on a recording policy associated with the initiating endpoint. The recording policy may specify far end recording, near end recording, or a prioritized order of far and near end recording. The call manager selected an anchor network device for copying the communication session based on the recording policy.

Configurable call recording policy

A method for effecting handoff of a communication session between a cellular telephone and a desktop telephone includes anchoring a communication session involving a remote device and a cellular telephone in an enterprise network such that signaling for the communication session passes through an element of the enterprise network; receiving an indication to handoff the communication session from the cellular telephone to a desktop telephone coupled to the enterprise network; placing the remote device in a holding state in response to the indication; and coupling the desktop telephone to the remote device to resume the communication session.

Handoff of communication sessions between cellular and desktop telephones

A method for implementing a SIP feature includes, in particular embodiments, establishing a communication session via a communications platform between a first and second user and receiving a request from a third user to join the communication session. The second and third users are from a plurality of users using a shared line. The method further includes integrating communications of the third user into the communication session. In particular embodiments the method includes establishing a communication session between a first and second user via a communications platform. The method also includes receiving a select request that locks the communication session so that a third user cannot resume the communication session with the first user. In particular embodiments the method includes receiving a request from a first user of a shared line to enable a privacy feature that reduces call information generated by the communications platform in remote state notifications.

System and method for implementing a session initiation protocol feature

A method is provided in one example embodiment and includes receiving a first portion of an identifier associated with a communication session involving a first endpoint that generated the first portion of the identifier. The method also includes receiving a second portion of the identifier associated with the communication session involving a second endpoint that generated the second portion of the identifier. The method can further include communicating a reservation request associated with a network resource to be allocated for the communication session. The reservation request includes the first portion and the second portion of the identifier.

System and method for providing a fate sharing identifier in a network environment

A system includes a first interface to connect with a network, and a second interface to connect with a telephone device of an enterprise. A unit controls a connection between the first and second interfaces for an outgoing call from the telephone device to a remote telephone device connected to the network. A processor subsystem coupled with the unit operates to initiate communications with a telephone device associated with a supervisor having authority to allow or deny the call. The processor subsystem also operates too present the supervisor with information that includes a purpose or reason for the outgoing call.
