xCALLY Shuttle can be currently installed on Linux CentOS 6.X MINIMAL distribution - 64 bit

Here you can find a link to download and install the CentOS 6 MINIMAL recommended release:

Note: CentOS 7 is also supported, however we STRONGLY recommend to use CentOS6 for your setup, because simpler to manage!

You can use a Virtual Machine or a Dedicated machine... It's up to you.

  • Up to 30 agents: 1 GB RAM to start, few CPU and HDD available.

  • Up to 100 agents: we recommend 2 GB RAM and 2 CPU.

  • More than 100 agents: at least 4 GB RAM and 4 CPU.


If you are planning to use complex IVR scripts and call recordings, please 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.


Please contact us in order to request the installation procedure.
