Abstract: A client device determines that a telephony outage is occurring. The client device connects to an on-premises telephony node using an encrypted password at the client device. The client device accesses a set of telephony services via the on-premises telephony node.

Abstract: A communication session is established between a device of a first user and a device of a second user. An input is received from the device of the first user. Based on the input, an external bypass step handler is communicated with to modify a property of the communication session. The communication session is then continued with the modified property. Continuing the communication session with the modified property may include maintaining a signaling channel associated with the communication session and changing a destination of a media stream of the communication session.

Abstract: An on-premises telephony node of a premises where telephony services are accessed obtains, from a telephony server, stored data associated with a network-based telephony service. The network-based telephony service includes at least one of an automated receptionist service, a call queue service, or a shared line group service. The on-premises telephony node receives an indication that the telephony server is unable to provide the network-based telephony service. The on-premises telephony node provides, in response to the indication, the network-based telephony service based on the stored data.

Abstract: A session border controller (SBC) that is separate from a telephony server associated with a destination telephony address receives an initiation request for a telephone call from an originating telephony device to the destination telephony address. The SBC attempts to connect the originating telephony device to the telephony server. Upon failing to connect the originating telephony device to the telephony server, the SBC connects the originating telephony device to a backup address associated with a distribution group. The SBC causes connection of the telephony device to a device of the distribution group via the backup address.

Abstract: A telephony server providing telephony services to a destination telephony address receives an initiation request for a telephone call from an external telephony device to the destination telephony address. The telephony server determines, based on a stored setting associated with the destination telephony address, whether call forwarding is enabled by the destination telephony address. Based on determining that the call forwarding is not enabled, the telephony server provides telephony services for the telephone call by the telephony server. Based on determining that the call forwarding is enabled, the telephony server connects the external telephony device to a session border controller associated with the call forwarding. The session border controller provides the telephony services for the telephone call.

Abstract: A communication session is established between a device of a first user and a device of a second user. An input is received during the communication session from the device of the first user. The input indicates a request to update an original property of the communication session associated with a path of media communication between the device of the first user and the device of the second user. An external bypass step handler associated with the input is identified. The external bypass step handler is communicated with to update the original property of the communication session to obtain a modified property. The communication session is continued with the modified property.

Abstract: Transformer-based message prioritization is performed to determine one or more messages for a user of a unified communications system to prioritize. A server of a unified communication system determines one or more intents of a user. The one or more intents are represented in natural language. A transformer engine of the server obtains a set of messages of the user. The transformer engine determines relevance scores for one or more messages of the set of messages based on the one or more intents and natural language information of the one or more messages. The server causes display of at least a subset of the set of messages based on the relevance scores.

Abstract: A communication session is initiated via a server device between a customer device and an agent device. A Dual Tone Multi-Frequency (DTMF) key sequence is indicative of a rerouting request of an audio stream of the communication session is received from the agent device. In response to receiving the first DTMF key sequence, the server device transmits the rerouting request to a third-party device. The rerouting request indicates that the third-party device is to receive the audio stream from the customer device without the audio stream passing via the server device and that the third-party device is to process a transaction with a user of the customer device. An indication is then received from the third-party device that the transaction is completed. In response to receiving the indication, the audio stream is transmitted to the agent device via the server device without passing through the third-party device.

Abstract: A method for preparing controlled phase alloys useful for engineering and hydrogen storage applications. This novel method avoids melting the constituents by employing vapor transport, in a hydrogen atmosphere, of an active metal constituent, having a high vapor pressure at temperatures .apprxeq.300 C. and its subsequent condensation on and reaction with the other constituent (substrate) of an alloy thereby forming a controlled phase alloy and preferably a single phase alloy. It is preferred that the substrate material be a metal powder such that diffusion of the active metal constituent, preferably magnesium, and reaction therewith can be completed within a reasonable time and at temperatures .apprxeq.300 C. thereby avoiding undesirable effects such as sintering, local compositional inhomogeneities, segregation, and formation of unwanted second phases such as intermetallic compounds.
