For up to 100 concurrent agents

• For Operating System and services: 8 vCPU, 16 GB RAM, 200 GB HDD

• For recording files: Disk Space (in bytes) = [Number of Calls × average duration (seconds)× bit rate /8] x 2
  for example;
  Calls in a month: 30000
  Average duration: 3 minutes = 180 seconds
  Bit rate for G711: 64 kbps
  So space required for one month of calls = (30000 x 180 x 64000/8) x 2 = 864000000000 bytes = ~ 80.46 GBs

Bandwidth Requirements:

Audio:

• Minimum Bandwidth: Approximately 150 kbps per stream.

• Optimal Bandwidth: 150-200 kbps per stream to ensure high-quality audio without compression artifacts.

QoS Parameters for Both Client and Server:

• Packet Loss:
  < 0.5%: Ensures high-quality audio without significant degradation. Packet loss beyond this threshold can lead to noticeable quality issues.

• Jitter:
  < 30 ms: Keeps variations in packet arrival times low, reducing audio distortions. Maintaining jitter within this range is crucial for consistent quality.

• Latency:
  < 100 ms: One-way latency within this range helps maintain natural conversation flow without noticeable delays. Lower latency is critical for real-time communication.

• Traffic Prioritization:
  Audio data should be prioritized over other network traffic: Ensures that voice quality remains consistent, even under network congestion. Implementing QoS policies that prioritize audio packets can significantly improve call reliability and clarity.
