Solution Prerequisites
Hardware Sizing
The following lists the machine specifications for up to 100 concurrent agents deployment, with no other EF components installed on the VM.
vCPU | vRAM | vDisk | Notes |
2 cores (2.60GHz, 2 processors) | 4 GB | 1x100 GB mounted on / | In case MSSQL server is installed on a separate machine |
| 4 cores (2.60 GHz, 4 processors | 8 GB | 1x100 GB mounted on / | If MSSQL server is installed on the same machine as the wallboard stack |
For HA, the same specifications would be doubled for two machines.
To get machine specifications for a larger agent volume and/or with other ExpertFlow products in a co-resident deployment, please get a quote from ExpertFlow or contact your ExpertFlow Account Manager.
Software Requirements
OS Compatibility
The following OS software is required on the server:
Item | Version | Notes |
CentOS | 7.x updated to the latest packages (use Yum update) | Administrative privileges (root) are required to follow the deployment steps. |
Database Requirements
Item | Notes |
| MS SQL Database Server 2016/2017 Express/Standard/Enterprise | For clustered SQL Server installation, the customer will be responsible to provide the cluster. For stand-alone DB deployment, DB (2017 express) will be included within docker containers. |
| Microsoft SQL Server 2017 | Microsoft SQL Server 2017, Microsoft Corporation Express Edition (64-bit) on Linux (Ubuntu 16.04.5 LTS). Only valid in case of a non-HA deployment. |
Docker Engine Requirements
| Item | Notes |
Docker CE 18.06.0+ |
Browser Compatibility
Item | Version | Notes |
Firefox | 73.0.1 (64-bit) | |
Chrome | Not tested | Some UI elements might not render properly. A full-blown testing cycle can be carried out on demand. |
| IE | Not tested | Not supported |
Cisco Unified CCX Compatibility
Tested with the CCX version 11.5 and 11.6 Assumed to work on higher versions as well. An on-demand testing cycle can also be executed on older versions of CCX.
Cisco Unified CCE Compatibility
Tested with the CCE version 11.5. Assumed to work on higher versions as well. An on-demand testing cycle can also be executed on older versions of CCE.
Wallboard Reporting/ Display Device
The provisioning of reporting devices is partner/customer's responsibility. For reporting device, one of the following hardware solutions must be provided to display wallboard views in the production environment.
- An existing PC with a pre-installed OS, Monitor or LCD for wallboard display OR
- A Smart LCD with an embedded browser to open the wallboard view OR
- A raspberry pi device with OS installed with an LCD to display.
For raspberry pi device's details, see https://www.raspberrypi.org/products/raspberry-pi-3-model-b/
Port Utilization
The following ports should remain open on the Firewall. The local security policy and any antivirus should also allow open communication on the following ports.
Type | Source Host | Source Port | Destination Host | Destination Port |
HTTP | Enterprise web user | any | Dashboard & Wallboards | 80 |
HTTPS | Dashboards & Wallboards server | any | Dashboard & Wallboards | 443 |
| UDP/TCP | Dashboards & Wallboards server | any | MS SQL Server (CCE DB) | 1433 |
System Access Requirements
Deployment Privileges
Administrative privileges (root) on the machine are required to follow the deployment steps. The Internet should be available on the machine where the application is being installed and connections on port 9242 should be allowed in the network firewall to carry out the installation steps.
Provision Database and a user on SQL Server Cluster
The following database and the privileged SQL user is required to connect to the application database. The application will create its tables and other schema objects itself after connection.
- Create a wallboard application database with the name EFWallboard.
- Create an SQL Server User EFUser with a database role db_owner on the EFWallboard database.
Integration with UCCX
To read CSQs and agents list from CCX, we need admin user credentials to access UCCX Configuration APIs to fetch the list of CSQs, agents, and teams.
To access the Cisco CCX database remotely via the wallboard application, CCX reporting user (uccxhruser) password is required.
Integration with UCCE
Since we need access on the Cisco AW database remotely, create an SQL server user, EFUser, with db_datareader role on the Cisco AW database.
Time Synchronization Requirements
If the system dates and times are not synchronized, the system can produce unpredictable results. Therefore, the EF applications and Cisco Contact Center should have their time zone and date/time properly configured, according to the geographic region and must be synchronized.
To configure the time zone, please see the instructions from the hardware or software manufacturer of the NTP server. The application servers should be synchronized. This synchronization should be maintained continuously and validated on a regular basis. For security reasons, the Network Time Protocol (NTP) V 4.1+ is recommended.
