🛠️ Call Center Terms and Concepts

Glossary of Key Terms:

  1. CRM (Customer Relationship Management) A system to manage customer interactions and data, enhancing sales and service efficiency.

  2. ACD (Automatic Call Distribution)
    Routes incoming calls to the most suitable agent based on pre-configured rules.

  3. IVR (Interactive Voice Response)
    Automates call handling with menu options and inputs via voice or keypad.

  4. CTI (Computer Telephony Integration)
    Links phone systems with computers for advanced features like click-to-call and caller info display.

  5. PBX (Private Branch Exchange)
    A private telephone network for handling internal and external calls in an organization.

  6. SIP (Session Initiation Protocol)
    Facilitates real-time communications such as voice, video, and messaging over IP.

  7. VoIP (Voice over Internet Protocol)
    Transmits voice communication over the internet, reducing costs and increasing scalability.

  8. FXO & FXS (Foreign Exchange Office & Station)
    Interfaces for connecting PBX systems with analog lines and devices.

  9. QoS (Quality of Service)
    Ensures high-quality audio by managing telecommunication network traffic.

  10. DID (Direct Inward Dialing)
    Enables callers to connect directly to specific extensions.

  11. UC (Unified Communications)
    Combines various communication methods like voice, video, and messaging into a single platform.

  12. TTS & ASR (Text-to-Speech & Automatic Speech Recognition)
    Converts text to speech or recognizes spoken language for automation and accessibility.

  13. API (Application Programming Interface)
    Allows integration between call center systems and third-party applications.

  14. AWS (Amazon Web Services)
    Cloud hosting services commonly used for scalable telephony solutions.

  15. MPLS (Multiprotocol Label Switching)
    Ensures fast and reliable data transmission across networks.

  16. KPI & NPS (Key Performance Indicator & Net Promoter Score)
    Metrics to measure call center performance and customer satisfaction.

  17. ANI (Automatic Number Identification)
    Identifies the caller's number for routing or tracking purposes.

🌐 Call Flow Architectures

Inbound Call Flow

  1. Caller dials the organization’s number.
  2. BTCL Lines → FXO Gateway → PBX → IVR.
  3. Calls are routed to the appropriate agent or department.

Outbound Call Flow

  1. Agent initiates a call from the PBX system.
  2. PBX → FXO Gateway → BTCL Lines.

Inter-Branch Communication

  1. SIP Trunking connects branch PBXs to the main system.
  2. Internal calls are routed through secure SIP protocols.

🚀 Key Features of Call Center Systems

  • Scalability: Handle increased call volume or integrate new branches effortlessly.
  • Reliability: Maintain operations even during internet downtimes with local PBX systems.
  • Security: On-premise telephony solutions minimize external vulnerabilities.
  • Cost Efficiency: Reduce communication costs using VoIP and optimized routing.
