This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call class of service. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or class of service is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or class of service, along all possible routes.

The invention discloses a voice trunk circuit access method, a voice trunk circuit access device, a mobile terminal and a storage medium, used for achieving unified management in voice communication.The method comprises the steps of achieving regular expression configuration of each route and synchronizing the same into a configuration file of a background server, an analyzing a call request, performing regular matching, learning a conveying circuit and performing a header field modification; setting a data interface, periodically updating and caching black and white list data, performing data matching on a call number, and executing a conveying or call prohibiting command after recognition; setting a number affiliation corresponding table, achieving the query of number affiliation, presetting a routing rule, and achieving a local call; recording the call, and performing unified record management; and achieving a middle agent, setting the routing rule, and achieving call reconnectionwhen a receiving terminal is unresponsive due to a gateway fault. According to the method, device, mobile terminal and storage medium provided by the invention, the unified management, deployment, charging and recording of the trunk circuit are achieved, so that the access to the call platform becomes simpler and quicker, and the configuration is reduced.

The present invention provides a system and method of processing multi-area access voice data of a distributed call center. All the incoming calls are accessed into a protocol conversion module through the voice trunk circuit of an access area; the protocol conversion module is configured to convert the multi-area incoming calls following the transport protocol of the voice trunk circuit to the call following the internal network communication protocol of enterprises and transmit the call to the gateway of the access area; the gateway is configured to generate the only one identification information aiming at the call, generate a CDR daily of call building, generate a CDR daily of call connection after the call is putted through, and generate a CDR daily of a call end after the call is finished; a collection server is configured to respectively obtain the CDR daily of call building, the CDR daily of the call communication and the CDR daily of call end, inquire the basic information of the CDR daily and store the basic information in a database. According to the invention, the real-time obtainment of multi-area voice trunk circuit communication information is realized.

A communications network connected to a plurality of communications lines and method of managing connections to the network. The presence of an interface connection to a communications line is detected and initialized for signaling. First, the interface connection is initialized for a first signaling protocol, e.g., CCS. If initialization is successful, the connection uses that first signaling protocol. If not, the interface connection is initialized using a second signaling protocol, e.g., CAS. If initialization to the second protocol is successful, the connection uses that second signaling protocol. Otherwise an error message is returned.

The invention provides a line state processing method and an apparatus thereof. The method comprises the following steps of through a network telephone VOIP supporting a calling function of a calling subscriber and a simulation relay plate supporting a telephone function of a calling terminal, executing calling processing to a called terminal, wherein the simulation relay plate is connected to a rack jumper wire; according to the VOIP and/or information fed back by the simulation relay plate, determining a calling processing result; and according to the calling processing result, determining a line state of the rack jumper wire. In the correlation technology, a person verifies the rack jumper wire so that verification complexity is high and efficiency is low. In the invention, the above problems are solved; a problem that later maintenance cost is increased because of a fault in a process of manually verifying the rack jumper wire is avoided; and work efficiency is increased.

The invention relates to an IP-PBX reservation automatic callback method, terminal equipment and a storage medium, and the method comprises the steps: when an extension receives a call request in a busy hour state, sending a prompt message whether to reserve a callback or not to a calling party in the call request; when an appointment callback confirmation message replied by the calling party is received, constructing a corresponding appointment extension message; and detecting whether the corresponding called party is in an idle state at regular time according to the appointment extension information, if so, initiating callback to connect the call between the calling party and the called party, and deleting the corresponding appointment extension information after the call is connected. According to the invention, under the condition that the call of the called party is not connected, the reservation callback can be automatically carried out, and when the call of the called party is hung up, the callback is timely carried out to communicate the two parties of the call, thereby promoting the improvement of the communication efficiency.

A communication device includes: a signal generator configured to generate a first signal and supply the first signal to a telephone line; a terminator having a variable terminal impedance as seen from the telephone line; a detector configured to detect a difference between the terminal impedance and a line impedance of the telephone line; and a controller configured to determine the terminal impedance so that the difference is reduced.

The invention relates to a protection system for a foreign exchange office. Voltage division is carried out when outside continuous high voltage appears on the protection system; a first-level surge protection module is adopted to bleed outside instant high voltage interference emerging in the protection system; a difference mode filtering module and a common mode filtering module are adopted to carry out difference mode filtering and common mode filtering on output signals of the foreign exchange office; finally a rectifier module converts the alternating-current signals into direct-current signals for work of a backward stage circuit. Most voltage of the whole circuit can be divided by adopting a current limiting module, and the first-level surge protection module bleeds surge high pressure in the circuit. The anti-interference capacity of the circuit can be improved, and the requirement for 4-level surge protection is met. After difference mode filtering and common mode filtering, it can be ensured that the power curve of the output signals meets the requirement, and good radiation performance is achieved.

A multifunctional analog TRK circuit board is designed so as to serve as both loop, ground start, DID, E&M, ring down and both way TRK. Thus, the various analog TRK circuits are embodied in a single TRK board, thereby increasing productivity compared to the conventional system requiring separate TRK circuit boards. The multifunctional TRK circuit is selectively controlled to provide desired TRK functions.

A method of testing trunks grouped in tributaries to evaluate interoffice transmission quality across a TDM network of all trunks in the office. The method includes performing a testing cycle testing only one trunk in each tributary in the central office to verify transmission quality. Testing includes setting up an interoffice connection to the one trunk, performing a transmission test on the one trunk. The method can also include attempting a connection to every trunk in each tributary in the testing cycle. The method can also include performing a plurality of testing cycles until all trunks in the central office have been tested, wherein each testing cycle includes testing one untested trunk in each tributary.
