Dynamic routing dial testing method and system for intelligent dispatching switched telephone network

The invention discloses a dynamic routing dial testing method and system for an intelligent dispatching telephone switching network, and relates to the technical field of power grid dispatching. The method comprises the following steps: constructing a telephone switching network routing dial test platform, and collecting site information, routing data and position information to construct a routing information base; and determining an abnormal route by executing the test path and comparing a test result with the route information base. And reordering the abnormal routes according to the importance of the routes, and carrying out repeated dialing test. And rechecking the retest data according to the set abnormal tolerance, marking the route exceeding the tolerance, and outputting an alarm signal to a display terminal and a mobile terminal to remind a worker to maintain in time. The method can improve the stability and reliability of the telephone switching network routing.

ActiveUS12652349B2Special service for subscribersSubstation callingTelephone terminalTelephone exchange
A telephone exchange apparatus includes an acquisition unit, an extraction unit, a specification unit, and a call control unit. In a case where an incoming call including a user ID is detected, the acquisition unit acquires event information of a user having the user ID, the event information indicating a schedule event. The extraction unit extracts location information of the user from the event information. The specification unit specifies a telephone terminal to which the user is most likely to respond among telephone terminals on a basis of the location information, the telephone terminals having been used by the user in a past. The call control unit causes the specified telephone terminal to ring.

Exchange, and telephone exchange method

ActiveUS12719983B2Terminal equipmentTelephone exchange
A first gateway registers an extension number of a terminal apparatus to an extension control means. A flow control means routes an outgoing call originated from the terminal apparatus and an outgoing call addressed to the terminal apparatus between the first gateway and a second gateway. When receiving the outgoing call originated from the terminal apparatus from the first gateway, the extension control means processes the outgoing call as an outgoing call from the extension number of the terminal apparatus. In addition, when an outgoing call addressed to the extension number of the terminal apparatus is made, the extension control means transmits the outgoing call addressed to the terminal apparatus to the first gateway.

Custom call flow implementation system and method based on IPPBX (Internet Protocol Private Branch Exchange)

ActiveCN120434335AInterconnection arrangementsTransmissionEngineeringTelephone exchange
The invention belongs to the field of network telephone exchange, and discloses an IPPBX (Internet Protocol Private Branch Exchange)-based customized call flow implementation system and method, and the system comprises a Web terminal, middleware and an IPPBX, the Web terminal is used for acquiring a call flow design customized by a user for the first call number; the middleware is used for acquiring a call flow design, converting the call flow design into JSON data, storing the JSON data, and notifying the IPPBX to update a first call number to a call flow configuration container; and the IPPBX is used for receiving a call request of a caller, requesting JSON data corresponding to a second call number from the middleware if the second call number carried by the call request is in the call flow configuration container, translating the JSON data into a call plan, and realizing a call flow according to the call plan. According to the invention, the call flow design is flexibly configured, the expandability is good, the IPPBX dynamically obtains the JSON data from the middleware, the number of configurable call flows is increased, and the memory occupation of the IPPBX is reduced.
