s7 In the connection of a number of telephone sets (1) to a private branch exchange (3) control information is communicated between the telephone sets and the exchange set in such a way that a bidirected conversion unit (19) is required. In order to provide a high degree of service at a reasonable cost the telephone sets (3) are collected in groups which share a generally small number of conversion units. By means of suitable control means (17) and switch units (15, 21) in the forwarding of control information, a suitable non-occupied conversion unit (19) can be selected.
摘要:
The invention relates to a method for establishing a telecommunications link (TC link) to and/or from a terminal device (10) via a mobile wireless network, wherein the terminal device (10) is connected to an exchange unit (20), a subscriber call number is assigned to the terminal device, the exchange unit (20) is connected to a mobile wireless gateway (30) to which a plurality of SIM cards (60) of the mobile wireless network (50) are or can be assigned, and a management system (40) is present to manage the SIM cards of the mobile wireless gateway (30). It is proposed that, for a signalisation of the TC link via the mobile wireless network, the subscriber call number of the terminal device (10) that represents the original destination address for an incoming TC connection request and the original sender address for an outgoing TC connection request, be replaced by the call number of a SIM card (60) of the mobile wireless gateway (30), so that a signalisation takes place between the mobile wireless network (50) and the mobile wireless gateway (30) with the call number of the SIM card (60) being used as the mobile wireless destination address or as the mobile wireless sender address. However, the original destination address or sender address is used for the signalisation of the TC link to the terminal device (10, 80) being called, wherein assignment information for assigning the original destination address to the mobile wireless destination address or for assigning the original sender address to the mobile wireless sender address is provided and/or communicated by the management system (40). The invention further relates to a telecommunications facility and a management system for implementing the method.

Techniques for using billing services to manage a personal address book are provided. The techniques comprise receiving a call detail record (CDR) for a plain old telephone system (POTS) or a voice-over-IP (VOIP) call by a user. The CDR is created by a telecommunication carrier that routed the call. The CDR may be stored on a telecommunications server associated with the telecommunications carrier. Address information for the call is determined from the CDR. This address information is added to the personal address book for the user. This address information may be available for the user when using an IM client.

This invention relates to a method and apparatus for establishing telecommunications calls. An intelligent peripheral (3) is bridged to a call being dialed (from 4). If the intelligent peripheral recognizes a need to supply information for establishing a call, or for signaling a customer request, the intelligent peripheral supplies digits or characters on the customer's behalf for use by the switch (1). The peripheral optionally has speech recognition apparatus for interpreting customer requests and supplying the digits needed to implement that request.

Methods, systems, and computer program products for performing range-based directory number (DN) screening are disclosed. According to one aspect, the subject matter described herein includes a method for determining that a telecommunications device DN is within an allowed set of numerical ranges. The method includes creating a range tree for representing an allowed set of numerical DN ranges, wherein each range is defined by a numerical upper and lower bound, and storing the range tree in a memory device; receiving a telecommunications device DN to be analyzed; traversing the range tree from a root node of the tree, based on analyzing each digit of the DN, until a leaf node is reached; and determining, based on an attribute associated with the leaf node reached, whether the DN is within the allowed set of ranges.
摘要:
A telephone connection is established between a first terminal and a second terminal. The first terminal is presumed to be associated with a subscription in a first home telephone network in which the terminal is identified by a first network identity. Correspondingly, the second terminal is presumed to be associated with a subscription in a second home telephone network in which the second terminal is identified by a second network identity. A host resource routes a call from the first terminal to the second terminal based on a combination of the first network identity and a first common telephone number in the first home telephone network dialed by the first terminal. The first common telephone number is selected such that it is unique and is adapted to be shared among a group of users in the first home telephone network.
