Hardware Requirements

The following overview was created for AskoziaPBX 4.0. Older versions have slightly lower hardware requirements.

CPU and RAM

The user numbers in the following overview refers to the number of IP phones registered at AskoziaPBX. We assume that on average max. 50% of the users speak at the same time (concurrent calls) using the codecs G.711 or GSM. The system can handle 100% of the users speaking at the same time in exceptional cases, however, that doesn't leave CPU power reserves for high performance features like conferencing, call recording, call control CTI, virtual fax or the usage of HD codecs.

Especially call recording requires a lot of CPU and storage performance. If that is a key feature of your telephony, make sure the hardware is dimensioned accordingly.

Storage

We recommend to equip the system AskoziaPBX is running on with two separate storage drives. One drive for the system (AskoziaPBX) and one for data (voicemails, voice prompts, call recordings, virtual fax archive, logs, call detail records etc.).

For embedded systems we recommend two separate physical drives. For virtual environments (Virtual Machines) we recommend two separate virtual drives. The size of the data storage differs drastically depending on the amount of data stored there.
