Examples disclosed herein involve receiving a request from a calling device to establish a communication session between a mobile device and the calling device, the mobile device assigned a virtual telephone number, retrieving location information corresponding to a location of the mobile device from a location register, and sending a redirect to a session border controller (SBC) to establish the communication session between the calling device and the mobile device based on the location information.

Volume leveler controller and controlling method are disclosed. In one embodiment, A volume leveler controller includes an audio content classifier for identifying the content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner based on the content type as identified. The adjusting unit may configured to positively correlate the dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.

A method, a device, and a non-transitory storage medium provide to receive a trigger to initiate a media session that is to be supported by a control channel and a media channel; generate a first Short Message Service (SMS) message, which includes a first Session Initiation Protocol (SIP) message configured to initiate the media session, in response to the trigger; transmit, via non-access stratum as the control channel, the first SMS message that includes the first SIP message to a server via a mobility management entity, in response to the generation; determine whether a bearer for the media channel is already established; establish the bearer in response to a determination that the bearer is not already established; use the bearer as the media channel in response to the establishment; and use the bearer as the media channel in response to a determination that the bearer is already established.

Integration of VoIP phone services with Intelligent Cloud Voice Recognition for emergency services overcomes limitations of conventional residential telephone technology to inexpensively provide more useful and advanced residential telephone services. For example, in an embodiment, a communication method may comprise establishing a communications session between either a user device and a telephone system or between a user device and voice recognition system, if the communications session is between a user device and a telephone system, extending the communications session to include a voice recognition system, if the communications session is between a user device and a voice recognition system, extending the communications session to include a telephone system, providing voice or speech information to the voice recognition system from the user device, and performing at least one function with the voice recognition system based on the provided voice or speech information.

Techniques for facilitating messaging in a group-based communication system between a calling device and one or more client devices. A first user operating a calling device may send a request to a call server computing device to send a call-based communication via the group-based communication system. The call-based communication may include voice or textual data. The call server computing device may receive the call-based communication and may format the call-based communication to send to the group-based communication system. The call server may send the formatted call-based communication to the group-based communication system for presentation via the one or more client devices.

An embodiment of the system for publishing events of a telephony application to a client includes a call router that generates events from the telephony application and an event router that manages the publication of events generated by the call router and that manages the subscription to events by clients. The system can be used with a telephony application that interfaces with a telephony device and an application server

Systems, methods and apparatuses for implementing enriched calling services for devices may include a first User Equipment (UE) that sends a call request to an IP Multimedia Subsystem (IMS) Core network and a presence server. The IMS core network may determine that the first UE supports enriched calling services and may enable the first UE to perform an enriched calling operation. The IMS core network may forward the call request to a terminating device, such as a second UE and/or a computing device, with the enriched calling operation.

A unified ecommerce platform system that enables sellers to acquire in depth insight into their business market and consumers utilizing a centralized cloud-based platform with enhanced consumer purchasing and information gathering abilities and allows users enhanced granular security tools and information for purchase.

Aspects of the subject disclosure may include, for example, including a processing system for performing operations for determining service requirements of a call session at first user equipment associated with a communication network, determining a first codec to facilitate the call session at the first user equipment according to the service requirements of the call session, searching a session border controller table according to the first codec to obtain a first resource identifier associated with a first session border controller type to facilitate the call session at the user equipment, receiving a first address of a first session border controller associated with the communication network from a domain name server associated with the communication network responsive to a first query including the first resource identifier, and sending a first transport protocol message to the first session border controller according to the first address. Other embodiments are disclosed.

Techniques for preventing denial of call transfer are provided. For example, a method, comprises: indicating, in an apparatus, that a call pull is initiated; categorizing, in the apparatus, an access attempt occurred for the call pull as a mobile-terminated access attempt; and making, in the apparatus, the access attempt to a network by transmitting a message to enable a process for the call pull, wherein the message includes a cause value set according to the categorization of the access attempt. The method may be performed by a user equipment (UE).
