If you are planning to use complex IVR scripts (DB access and custom scripts) consider to double the RAM.

If you need to store a lot of logs and call recordings, please evaluate a large HDD space. Calls recorded in wav format need about 1MB per minute, in GSM format about 300k per minute. CentOS default root partition is 50 GB, if you need more space set partition size manually during installation.

For security reasons, please consider to install a proper firewall in front of your XCALLY server, especially if it is deployed on the Cloud.


How-to scale

Scalable architecture

For large scalable deployments on one hand, and to be able to interact with the Motion DB from external application on the other hand, without affecting the operation, we suggest at least 3 Linux CentOS6.X servers, like in the following example.

Please contact our XCALLY Team for help and more details about this scalable deployment solution.




Client side

Google Chrome or Firefox browser

Windows 7,8,10 with .Net 3.5 installed (to use the XCALLY Motion omnichannel phonebar)
Apple or Linux with Google Chrome (and external SIP clients)

Browser compatibility

In order to use the XCALLY Motion web application, you need to use Google Chrome or Mozilla Firefox.

In particular, the application has been tested with minimum Google Chrome (v46) and Firefox (v41.0.2) on Windows (8.1/10) and Mac OS (Yosemite/El Capitan).

Optionally you can use Microsoft Edge 25.10586 (tested on Windows 10)


Firewall

Remember you will need at least ALL the following open ports to/from your server and your agent seats.

TCP: 22, 80, 443, 5060, 5061

UDP: 5060, 5061 and the whole range from UDP 10000 up to 20000 included

ICMP: open! You need to be able to ping your XCALLY server from the agent computers

Please look also at the CentOS iptables rules and modify those in the file: /etc/sysconfig/iptables adding new IP addresses where and when you need. The command service iptables restart will apply the new rules you have modified **
The following commands will stop and remove your iptables firewall - in case you would like to prefer to manage the security with another external firewall:
service iptables stop
chkconfig iptables off 


Please note the Motion installer will add security rules inside your CentOS6.X iptables, restricting the audio VoIP access from private IP addresses and XCALLY operation center.


**Please ask only your system administrator with proper skills to do it



Licenses

Please note that any change of any kind applied on your XCALLY server (i.e. CPU, memory, HDD, network etc…) can invalidate your XCALLY assigned license: for this reason any move and change of your XCALLY server must be carefully planned and notified to the XCALLY team.
