    • VOCAL System Requirements and Scalability
    • System Recommendations
      • The recommended hardware system to support the VOCAL system is:
        • 700 MHz, Pentium III Intel based PC.
        • 512 MB RAM.
        • 1 GB Hard disk space.
      • Feature Servers require 10KB of RAM per provisioned user.
    • Software Requirements
      • The following software should be installed:
        • Linux Red Hat Version 6.2 or later.
        • Apache Server.

    • Redundancy and Scalability (1)
      • Marshal Servers & Feature Servers:
        • Multiple Marshal Servers and Feature Servers can exist in a VOCAL system.
      • Redirect Servers:
        • Multiple Redirect servers can exist in a VOCAL system.
        • Each Redirect server contains the same information and registration information is shared between the Redirect servers.
      • Call Detail Record Servers:
        • A maximum of two CDR servers can exist in a VOCAL system.

      • Provisioning Servers:
        • A maximum of two Provisioning servers can exist in a VOCAL system.
        • If two Provisioning server exist is a VOCAL system, information saved on provisioning server is shared with the other provisioning server.
        • The Provisioning servers will synchronize information periodically.
