Solution Prerequisites

The following are the prerequisites for setting up Voice recording solution under different deployment profiles.

	Voice Recording Solution

	Voice Recording Solution
Hardware Sizing
For up to 100 concurrent agents	4 vCPU, 8 GB RAM, 500 GB HDD
Software Requirements
Host Operating System - Debian 10 Docker Community Edition 18+ Docker Compose 2.15.1 Git Client 1.8+ FusionPBX (Only for EFCX) Postgresql (Only for EFCX)
System Access Requirements
Administrative privileges (root) on the host machine are required to proceed with installation.
Network requirements
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. Minimum Bandwidth: Approximately 150 kbps per stream.

Port Utilisation

The local security policy and firewall should allow open communication on the following ports.

Type	Source Host	Port	Destination	Notes

Type	Source Host	Port	Destination	Notes
HTTPS	voice-recording-solution	444	any	To access VRS front-end

Time Synchronisation

Communication between Voice Recording solution, Cisco CUCM, Cisco IP Phones (BIB enabled) carry timestamps. If the system dates and time are not synchronised the system can produce unpredictable results. Therefore, please make every effort to adhere to the following time synchronisation guidelines:

Voice Recording solution, Cisco CUCM, Cisco IP Phones (BIB enabled) should have their Time Zone and time configured properly according to the geographic region and synchronised. To configure the time zone, please see the instructions from the hardware or software manufacturer of NTP server. Voice Recording solution and Cisco CUCM should be synchronised to the second. This synchronisation should be maintained continuously and validated on a regular basis. For security reasons, Network Time Protocol (NTP) V 4.1+ is recommended.
