Realized Functions

1. Dispatch Console Grouping: Dispatch consoles can be grouped, and consoles in the same group can be assigned independent numbers. When an incoming call is made to the group, all consoles in the group will ring, and any console in the group can answer the call. Consoles in the same group share a hold queue; after one console puts an incoming call on hold, other consoles in the group can resume the call.
2. Dispatch Console Numbers: Each dispatch console has a unique number, allowing users to call a specific console. Consoles in a group have a general number for users to call all consoles in the group simultaneously, and there is a universal number for users to call all dispatch consoles in the system at once.
3. Instant Call Connection: Dispatch consoles can directly call users via dedicated keys, with user key numbers configurable on the terminal. Consoles can also make calls via the numeric keypad.
4. Auto Answer: After one ring, the keypad dispatch console automatically activates the microphone and audio amplifier to start a call.
5. Off-hook Answer: The keypad or PC dispatch console can answer the first incoming call in the queue by picking up the handset.
6. Key Answer: The dispatch console can answer the first incoming call in the queue by pressing the “Answer” key.
7. Selective Answer: When multiple users call the dispatch console at the same time, the console can select any one call to answer first. While the console is on a call with the selected user, other callers will continue to hear the ringback tone and wait for an answer. If there are unanswered calls while the console is in a call, the console will keep ringing.
8. Group Answer: When multiple users call the dispatch console simultaneously, the console can answer all incoming calls (internal or external) at once. In group answer mode, all answered users can communicate with each other, and also with the dispatch console.
9. Group Call: The dispatch console can call multiple users and user groups simultaneously. In group call mode, all called users can communicate with each other, and also with the dispatch console.
10. Broadcast Conference: Only the dispatch console can speak, and participants can only listen. The broadcast targets can be set by the dispatch console.
11. Scheduled Conference: A full-duplex conference that allows external users to participate. The entire system supports 128-party conference calls, with multiple conferences held simultaneously. The dispatch console can mute participants, allow them to speak and disconnect their calls. If a participant leaves the conference early, the system has a call recall function. The dispatch console can transfer new incoming calls into the conference.
12. Ad Hoc Conference: A full-duplex conference that allows external users to participate, with participants arbitrarily designated by the dispatcher when initiating the conference (up to 128 participants). The dispatch console can add participants by pressing user keys or dialing numbers when holding an ad hoc conference, and all dispatch consoles can hold ad hoc conferences at the same time.
13. One Number for Multiple Terminals: One user key on the dispatch console can correspond to multiple numbers. When dialing, all corresponding numbers ring simultaneously; once any terminal answers, the rest stop ringing. Registered phone numbers can be set to ring simultaneously through data configuration, and a ring delay can also be set (known as delayed ringing or sequential ringing).
14. Call Hunting: The dispatch console is equipped with a call hunting function, where one user key corresponds to multiple numbers. If the first number cannot be reached, the system automatically calls the subsequent numbers. The dispatch console can set the call hunting duration, and the dispatcher can press a key to end the call to the current number early and switch to the next one before the set duration expires.
15. Call Intrusion and Disconnection: The dispatch console has the authority to intrude into calls of lower-level dispatch users. When the console calls a lower-level user, the system automatically initiates call intrusion to form a three-way call. The console also has the authority to disconnect calls of lower-level dispatch users and can intrude into an ongoing call for negotiation of disconnection when the called user is busy.
16. Ringer Silence: The dispatch console can silence the ringer for incoming calls, with only the display showing new incoming calls without the console ringing. If the ringer silence is activated during a call, the console will not ring for the rest of the call and resume normal ringing after the call ends. If activated when the console is idle, the console will remain silent until the setting is canceled manually.
17. Call Rejection: The dispatch console can reject new incoming calls, either a single call or all incoming calls. After rejection, the caller hears a busy tone and the console stops ringing.
18. Call Transfer: The dispatch console can transfer incoming calls, enabling an internal or external user currently on a call with the console to switch the call to another internal or external user.
19. Call Hold and Switching: The dispatch console has a call hold function, supporting up to 3 held incoming calls at the same time, and the dispatcher can switch calls between the held lines.
20. Status Monitoring: Dispatchers can monitor the real-time status (e.g., idle, busy) of each dispatch extension via the console, with different statuses displayed in real time with distinct colors on the console interface.
21. Call Recording: All call records can be directly inquired on the dispatch console, and audio recording files can be played back and downloaded.
