  Services of various boards (MCU, REC, IPS, IPO, etc.) can be connected to the network via RJ45 cables, allowing users to manage remotely through WEB or client terminals.
• Full-Channel Recording
  Supports full-channel recording.
• Modular Design
  Allows flexible configuration of the total capacity based on customer needs, with hot-swappable support for all boards.
• Long-Distance Analog Access
  Long-distance analog user boards can connect analog terminals up to 10KM away.
• Redundant Hot Backup
  1+1 redundant hot backup is supported for MCU main control boards, secondary power supplies, primary power boxes, and full-channel recording boards.
• Reliability
  Passed 20,000-volt lightning protection testing; equipped with overcurrent/overvoltage protection and three-level lightning protection measures to ensure stable operation in harsh environments.

Function Introduction

• Comprehensive Hybrid Tandem
  Supports hybrid tandem between No.7, ETSI (PRI), No.1, SIP, loop, and other trunk interfaces.
• Full Extension Numbering
  2 groups of 0-20 digit variable-length full extension numbers.
• Prefix Management
  Complete system prefix management to meet complex professional networking requirements.
• Prefix Indexing
  8 major groups of system prefix index tables, providing 8 independent number processing strategies.
• Trunk Caller ID
  Trunks fully support caller ID for all types of loop or digital trunks.
• Call Information
  Complete call information for internal and external lines.
• Dialing Preprocessing
  Powerful dialing preprocessing function.
• Duplicate Numbers for Internal/External Lines
  Allows full or partial duplicate numbers for internal and external lines.
• Call Detail Recording
  Full recording of call details for all calls on the host, providing complete call process records.
• Board Fault Detection
  Advanced hardware board fault detection and automatic shielding functions; real-time board status visible on the backend.
• Alternative Trunk Routing
  Uses primary routing under normal conditions and switches to alternative routing in case of faults, with automatic recovery/switching.
• Data Backup
  Comprehensive system data backup and recovery functions.
• Virtual Operator
  Reduces operator workload. When an external call reaches a trunk with virtual operator enabled, it directly connects to the virtual operator for ringing and transfer; if busy, it cycles through operators sorted by physical number.
• Intelligent Voice Service
  By dialing specific function codes after picking up the handset, the dispatcher can broadcast system date, time, extension number, physical address, level, malicious call numbers, host version, and music, with clear and smooth voice for quick access to service information.
• Dual Numbers per Extension
  Each extension can have 2 phone numbers, both usable for calls.
• Extension Ring Cutoff
  Ringing stops immediately when the extension picks up the handset to avoid annoying ringtone noise.
• Distinctive Ringing for Internal/External Calls
  Different ring intervals for internal and external calls to help users identify call sources.
• External Coding
  Extensions can select a 1-14 digit external code as the caller ID when making outbound calls via digital trunks.
• Internal Line Grouping
  Extensions can be grouped for management, enabling one dispatcher to serve multiple user units.
• Malicious Call Query
  Extensions can query the last internal caller ID.
• Multi-Level Restrictions
  32 customizable levels for flexible permission management by users.
• Designated Trunk Outbound
  Extensions can dial to use a specific trunk for outbound calls.
• Call Transfer
  Supports transferring internal/external calls to internal extensions or external numbers (mobile phones/landlines). Four transfer modes: unconditional, busy, no-answer, and busy+no-answer. Users can set/cancel transfers via function codes.
• Busy Redial
  If the called extension is busy, the caller dials "3" during the busy tone and hangs up. The caller’s extension rings automatically when the line is free; picking up triggers the called extension to ring.
• Call Pickup
  Other extensions can dial a function code to pick up unanswered calls.
• Hotline Function
  If no dialing occurs within a set time (configurable) after picking up, the system automatically calls a preset internal extension (internal hotline) or external number (external hotline); supports automatic outbound trunk access without dialing an exit prefix.
• Do Not Disturb
  Blocks incoming calls during inconvenient times.
• Internal/External Conference Calls
  Supports conference calls with internal and external users (via loop, 2M, E/M, or IP trunks). Each conference allows up to 64 speakers and 128 participants; maximum 4 concurrent conferences.
• Internal/External Call Transfer
  Transfers internal/external calls to other extensions.
• Call Intrusion/Disconnection
  Allows intrusion into or disconnection of ongoing calls to prioritize important calls.
• Wake-Up Service (Alarm)
  For intelligent hotel wake-up; set times via extensions or operator, with automatic ringing at the set time.
• Unanswered Call Transfer to Operator
  External calls routed to an unanswered extension can be transferred to the operator; configurable ring count for transfer. (Set via no-answer transfer)
• Custom Voice Recording
  Users can record trunk prompt voices via phones.
• Built-in Voicemail
  Three high-quality voice prompts: main prompt, busy prompt, and no-answer prompt. Provides status voice (date, time, charges, extension number, etc.) and supports custom voice prompts.
• Ringtone Customization
  Plays music or audio instead of traditional ringtones before the called party answers.
• Call Bill/Charge Inquiry
  Queries or settles total charges for all or individual extensions within a period, with printable detailed and statistical bills.
• Three-Way Calling
  Enables three-way conversations, with options to hold or disconnect any party.
• Voice Navigation
  Guides external callers to designated extensions or sub-menus via voice prompts.
• Intelligent Trunk
  Records extension calls to external numbers. If the external number calls back, it is directly routed to the last dialing extension, bypassing navigation or operator.
• Secretary Function
  All calls to the boss are transferred to the secretary, who transfers important calls via flash hook.
• Blacklist
  Users can block unwanted external numbers by adding them to the blacklist.
