System requirements

Network Channel Requirement

An example of calculating the required channel bandwidth for different codecs for 30 simultaneous calls. PBX supports the most popular codecs:

• G.711 - 4.67 Mbps

• GSM - 1.68 Mbps

• G.722 - 4.67 Mbps

• G.729 - 1.38 Mbps

The calculation is approximate, when using the same codec on all devices connected to the PBX. Read more here.

Minimum system requirements

We recommend using two hard drives for PBX deployment.

• 800 Mb hard disk for the main system

• A 50+ Gb hard drive for recording conversations

• 1 (2 cores) x86-64 processor

• 2 GB of RAM

• Network Adapter

A PC with such parameters, in our tests, holds 38 simultaneous incoming calls under the conditions:

• 10 agents are connected to the queue (all online)

• Every second a new call comes in

• Music (MOH) is played to the client while waiting

• Modules on the PBX is not installed

Approximately, 1 hour of conversation takes up 14MB of disk space.
