A workload balancing technique enhances balancing of workloads processed by components of a telephone communication system configured to render telephony services over a computer network. The telephony services illustratively include private branch exchange (PBX) services suitable for customers with geographically dispersed telephone service demands. The workload balancing technique is invoked by the communication system to reduce contention among the components of the system, such as telephone access servers (TASes) coupled to a proxy router, when servicing telephony requests issued by the customers, thus enabling rendering of the telephony services in an efficient and cost-effective manner. As described herein, an available TAS is randomly selected to service a telephony request received by the proxy router from a network coupled to the communication system.

A method and system for least cost routing for mobile telephone calls between the United States and Mexico in such a way so that the call is separated into several call legs and the international portion or call leg is routed via a low-cost or no-cost route independently of the local call legs, essentially achieving an international call with local call rates. This uses a SIM card that automatically identifies any incoming or outgoing call and provides the ability to convert the call from an expensive international and/or roaming call to a local (free) call. Several slight variations are disclosed, and all embodiments have an integrated money transfer service that can be used with a very simple low-cost basic mobile phone using IVR, SMS and voice recognition, or can be accessed via the web or via a smartphone app.

Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises one or more baseband processors to generate a voice call invite message for a remote UE, and a memory to store the voice call invite message. The voice call invite message includes a header p-use-silence-period to indicate that the UE is configured to transmit or receive non-voice data during a silence period of the voice call.

A method and a system for establishing a communication session between a first communication device in a main communication network and a second communication device in a local communication network comprising a wireless network, the second communication device being located in the vicinity of a mobile device, the first communication device contacting an external phone number, wherein the external phone number is assigned to a unique identifier of the mobile device. The method comprises (i) the mobile device sending the unique identifier detectable on the wireless network; (ii) providing the unique identifier of the mobile device) and a local communication identifier to a service provider adapter; (iii) determining the location of the mobile device, associating the mobile device to the second communication device in dependence of its location.

Techniques for call intent notification for establishing a call are described. According to one or more implementations, a user of a first user terminal attempts to establish a call with a second user terminal. Based on determining that the second user terminal and/or a user of the second user terminal is not available to answer the call, a call intent notification is sent to the second user terminal. According to one or more implementations, the call intent notification includes a number that enables the second user terminal to establish a call with the first user terminal.

The present disclosure is directed to a method and system for routing communications. A plurality of communications-enabled devices are coupled to a communications network. Each communications-enabled device has a device identifier. A user-programmable database associates each of a plurality of user identifiers with a device identifier. A router circuit is coupled to the communications network through a portal communication device having a portal identifier. A user designates a destination user identifier when making a communication. The router circuit switches the call, directing the call to a destination device identifier responsive to the user-programmable database association between the destination user identifier and a device identifier. According to certain aspects, communications are directed to users and are routed to associated equipment, a user identifier serving as a virtual extension number. Users remotely program the database to direct their communications to communications-enabled devices at various destinations.

Duplex transmission of voice streams between mobile phone call applications and IM/VoIP service clients installed on smartphones is carried out by connecting audio outputs to audio inputs of smartphone audio interfaces. These voice communication applications can be installed on the same smartphone, on two different smartphones, or on one smartphone and one computer of any type. The inventive method contains connections both between the same type and between different wired and wireless audio interfaces of smartphones. As a consequence of the application of the technical result of the method for duplex transmission of voice streams, an invention is claimed for methods for implementing PBX with various types of routing, and a VoIP-Cell gateway for broadcasting voice traffic between a mobile phone client and a VoIP client running IP-PBX.
