Digital IP program-controlled telephone exchange has significant advantages over traditional telephone exchanges, and the following is a detailed point-by-point representation and summarization of its advantages:

  Fast transmission speed:

  Digital IP program-controlled telephone exchange adopts digital switching technology, signal transmission and processing are realized by computer, so the transmission speed is much higher than the traditional analog exchange.

  The sound quality of the call is clear and stable, and it supports the transmission of digital signals, so the quality of the call will not be degraded because of the interference of the signals.

  Stable operation:

  The connection of the switch is controlled by the program, which avoids the line failure that may occur in the traditional switch due to wiring error and other reasons.

  It has certain fault self-test and self-expansion ability, which can diagnose and repair line faults and other problems accordingly.

  Flexible functions:

  Flexible application expansion and function upgrading can be carried out through the program, with more perfect network application capability.

  Support a variety of communication interfaces and interface protocols to facilitate networking with other network devices.

  Flexible network configuration can be realized on demand to achieve network optimization and adjustment.

  Resource sharing:

  Characterized by resource sharing, it can unify the management and distribution of different business resources.

  Adopting unified storage management to realize effective management and scheduling of various resources.

  Provide users with flexible business management interfaces to facilitate independent business management and scheduling.

  Support multiple access methods and interface protocols:

  Support ordinary analog phone, IP phone, IP video terminal, soft terminal, IAD/AG access, to meet the different networking needs of customers.

  Provide PRI, NO.7, FXO/FXS narrowband interface to interconnect with PSTN and compatible with traditional PBX access.

  Supports VoIP control protocols such as SIP, IMS, and VoIP transmission protocols such as RTP, with strong compatibility.

  High system integration and good system compatibility:

  Integration of traditional switching, softswitch, and voice gateway functions, cost-effective equipment, easy to deploy and maintain.

  Supports traditional PSTN/PLMN, NGN/IMS communication networks and can interoperate with third-party communication systems.

  Advanced voice quality assurance:

  Supports multiple codecs, anti-jitter buffering, echo suppression, mute compression and other technologies to provide assurance for high quality transmission of voice and video.

  Operational-grade reliability design:

  Supports dual-machine hot standby, realizes automatic master and standby switching, and has a reliability of up to 99.999%.

  Cost-effective:

  Due to its open standard IP-based design, the products are highly interoperable with each other, saving the cost of maintaining proprietary equipment.

  Good scalability and relatively low cost when multiple branch phones need to be expanded.

  Reduces equipment costs by allowing direct use of inexpensive ordinary analog phones.

  Save long distance communication costs by utilizing the VoIP feature:

  By utilizing its VoIP function, users can make long-distance calls at the price of local calls, which greatly saves long-distance communication costs.

  To sum up, digital IP program-controlled telephone exchange shows significant advantages in transmission speed, operation stability, function flexibility, resource sharing, compatibility, voice quality, reliability and cost-effectiveness.
