System Status

The system status gives you an overview about the state of the PBX (see the picture below for an example).

The "Version" header shows you what version of the software you are running. The first number is the major software number, the second the minor software release and the third number the patch level. The fourth number is the build number.

The "License Status" shows the descriptive text of your license. If this field is empty, do no have a license. The text is defined in the license key, and can in principle have any value.

The "License Duration" shows you how long the license will last. If you have a permanent license, the PBX will tell you so on the status screen.

The "Additional license information" typically shows you the usage of accounts or extensions. The first number tells you how many accounts are in use, the second number shows you what is the maximum number of accounts.

The "Working Directory" line shows you where the PBX expects the audio and table data. If you want to backup your data, you should copy the data in this directory.

The "IP Addresses" helps you to understand which identities the PBX uses for the outside communication. The PBX first checks on which interface it will send a packet, and then changes it's identity accordingly in the SIP packet. This feature makes it possible to run the PBX on hosts that talk to the public Internet and the private Intranet at the same time without the need for an application layer NAT gateway.
- In Linux, the PBX will show what it was reading out of the system configuration. It shows what interface is associated with the IP address, the IP addresses itself, the address that is matched against the destination IP address and the netmask. At the bottom, it will also show the default IP address (IPv4 and IPv6) that will be used when there is no match.
- In Windows, it just shows the IP addresses. Because in Windows there is a system call that performs the neccessary steps, there is no need to show the routing details.

The "MAC Addresses" are used for licensing purposes. The PBX lists the MAC addresses that it could find on this system. Every time that you load the status web page, the system refreshes that table. This is important when you turn adapters on and off (e.g. wireless, VPN). The PBX ignores "virtual" MAC addresses like from VPN adapters.

The "Calls" entry tells you how many successful/unsuccessful calls were made on the system after restart. Successful calls are those calls that were in the connected state. For example, when the other side did not pick up, that call counts as unsuccessful. The CDR number in brackets shows you how many CDR entries the PBX keeps internally for listing purposes. If this number grows too large, you should consider making the Keep CDR Duration shorter. The Last number shows how many call objects are currently active on the system.

The "SIP packet statistics" shows how many SIP packets have been received or sent.

The "Emails" line shows you how many emails the PBX has successfully sent and how emails it tried. If the last email could not be sent successfully, you will see a special warning.

The "Uptime" line gives you information how long the system is running. The line format is days followed by HH:MM:SS. In Windows, you will also find additional information about the memory usage. The PBX will also show how many WAV file it has currently in memory (typically because there is IVR going on).

The "Media CPU Usage" field shows you the usage of the CPU over the last 24 hours. The graph shows the ratio between waiting and processing of the media thread of the PBX. This number is a good indication how well the CPU was able to keep the real-time requirements for processing media. The blue line shows the CPU load when new calls are being rejected because of performance problems. The yellow line shows you where the log is currently writing into the graph. The green fields show you the average load (averaged over a period of six minutes), and the blue lines above the green fields show you the peak usage of the CPU (averaged over a period of three seconds).

In the domain mode, you will see only a short version of this page.
