The following are the solution setup prerequisites.
Hardware requirements
A single VM required for NON-HA deployment.
For HA deployment, two VMs are required. Each machine should have the following hardware specifications. The two VMs will be referred by VM1 and VM2 in this guide.
Minimum requirement | |
|---|---|
CPU | 4 cores on each VM |
RAM | 4 GB on each VM |
Disk | Here is a general formula for the calculation of disk space For example, if you have a recording that is 60 seconds long, uses the G.711 codec (which has a sample rate of 8 kHz and a bit depth of 16 bits), and is recorded in mono, the file size would be calculated as: Using this formula, disk space can be calculated for number of daily calls and retention period. |
NICs | 1 NIC per VM |

Time Synchronisation
Communication between Voice Recording solution, Cisco CUCM, Cisco IP Phones (BIB enabled) carry timestamps. If the system dates and time are not synchronized the system can produce unpredictable results. Therefore, please make every effort to adhere to the following time synchronization 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 synchronized. 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 synchronized to the second. This synchronization should be maintained continuously and validated on a regular basis. For security reasons, Network Time Protocol (NTP) V 4.1+ is recommended.
Port Utilization
SIP Trunk configuration
