Installation

Install Lua libraries

  • SSH into the Debian server onto which the Media Server is installed.

    • Use command

      CODE 
      ssh username@server-ip

    • Enter user password and press ENTER.

    • Use command

      CODE 
      su

    • Enter root password and press ENTER.

  • Run the following commands, one at a time:

    • CODE 
      apt install lua-socket
sudo apt install lua-sec
sudo apt-get install lua-json
sudo apt-get install -y lua-dkjson

Configure IVR scripts and recordings

Deployment

  • SSH into the Media Server.

    • Use command

      CODE 
      ssh username@server-ip

    • Enter user password and press ENTER.

    • Use command

      CODE 
      su

    • Enter root password and press ENTER.

  • Confirm git is installed, and install it if is not.

  • Clone the Media Server scripts repository:

    CODE 
    git clone -b TAG https://efcx:RecRpsuH34yqp56YRFUb@gitlab.expertflow.com/rtc/freeswitch-scripts.git

    • Where TAG is the latest branch tag of the Media Server scripts repository obtained from here.

  • Navigate to the cloned repository to access the files:

    CODE 
    cd freeswitch-scripts

  • Alter the file name of cx_env.lua to cx_env{DN}.lua where {DN} is the dialing number of the IVR (Set in the CxIvr Dialplan section below).

    • e.g. for an IVR with a dialing number of 1555 the file would be named cx_env1555.lua.

      CODE 
      mv cx_env.lua cx_env1555.lua

  • Move the files ending in .lua  to the Media Server scripts folder:

  • CODE 
    mv *.lua /usr/share/freeswitch/scripts

  • Move any custom IVR scripts to the Media Server scripts folder:

    CODE 
    mv <custom-lua-IVR-script> /usr/share/freeswitch/scripts

  • Move the ivr_prompts folder:

    CODE 
    mv ivr_prompts /usr/share/freeswitch/sounds/

  • Assign read-write permissions to the ivr_prompts and scripts folder:

    CODE 
    chmod 777 -R /usr/share/freeswitch/sounds/ivr_prompts
chmod 777 -R /usr/share/freeswitch/scripts

Configuration

  1. Open cx_env{DN}.lua :

    CODE 
    vi cx_env{DN}.lua
    CODE 
    local config = {}
config = {
    -- Set to NAME or ID depending on whether queue field contains name or ID of queue
    queueType = 'NAME',
    -- Name or ID of queue to reserve agents from
    queue = 'Voice Queue',
    -- NOTE: Keeping queue and queueType as '' will cause CX to use the default queue set in the CX Voice channel
    -- queue = '',
    -- queueType = '',
    -- CxFQDN
    cxFqdn = "https://devops.com",
    -- API of voice connector for reserving an agent
    voiceConnectorApi = "http://VC-IP:VC-PORT/request-agent",
    -- Path of folder containing sound files that play during the IVR menu, DO NOT CHANGE
    ivr_prompts_folder = "/usr/share/freeswitch/sounds/ivr_prompts/",
}
return config

  2. Press the "I" key to enter editing mode.

  3. The queueType field can contain one of two values:

    1. 'NAME'

    2. ''

  4. The queue field can contain one of two types of values, based on what the queueType field above contains:

    1. Name of the Agent Queue e.g. Support Queue (If queueType contains 'NAME') This name can be obtained from Unified Admin from the Queues section.

    2. Empty string i.e. '' (If queueType contains '')

  5. If queue and queueType are set to '' , then the call will be routed to the default queue set for the CX Voice channel in Unified Admin.

  6. The voiceConnectorApi field will contain a URL in the following format:

    1. http://VC-IP:VC-PORT/request-agent

    2. Replace VC-IP and VC-PORT with IP address and port of the voice connector.

  7. The cxFqdn field contains the fully qualified domain name of the EFCX:

    1. https://devops.com

    2. Replace https://devops.com with the EFCX domain name.

  8. The ivr_prompts_folder field contains path to the ivr_prompts folder. Leave it at the default value.

  9. Save and exit the file by pressing the Esc key, entering :wq and pressing ENTER.
