How can I be notified when Asterisk reports issues in its logs, e.g. if a connection is lagged? One way is to include the Asterisk logs in the logs that are monitored by Linux’s daily logwatch.More...

A client has an old PBX in a Flash 1.3 installation running Asterisk 22.214.171.124. I’ve upgraded their Linksys SPA942 phones to the latest firmware, version 6.1.5(a). Can we get Busy Lamp Field (BLF) functionality to work on the empty line keys?More...

I’m using Asterisk 1.8.5 under FreePBX 126.96.36.199. My endpoints (Polycom IP430 phone, SPA3102 ATA) and my ITSP all support the G.729a codec. I wanted to test audio quality using this compressed codec.More...

Sometimes the trickiest errors are the ones you should ignore.
I’m running PBX in a Flash, based on CentOS 5.2, on a Dell PowerEdge 1500SC. Back in February, I got a segmentation fault error and after some discussion on the PBX in a Flash forum, concluded that I needed to replace the hardware or at least the memory. Now I’m not so sure.More...

I have PBX in a Flash set up to create a daily backup and FTP the file to a Windows server. But how do I get rid of the old backups on the Linux machine, which is running CentOS 5.2? A cron job can do the deletes, but I also want a list of the deleted files delivered with my daily Logwatch 7.3 report.
Here’s what I did:More...

Back in November 2008, I blogged about Setting Up PBX in a Flash, Part 1: Configuring a Virtual Machine. That article discussed running PBX in a Flash (PiaF) under Microsoft Virtual PC or Virtual Server 2005. Within a couple weeks, I abandoned the virtual machine approach and published Moving PBX in a Flash from a Virtual to a Physical Machine.
Recently I’ve been testing Microsoft’s free bare-metal hypervisor, Microsoft Hyper-V Server 2008 R2. Especially now that Hyper-V supports Red Hat Enterprise Linux, could Hyper-V be the answer to virtualizing PiaF on a Microsoft platform?
Let’s try it and see what happens.More...

Although Kaseya doesn’t yet have a native Linux agent, it does allow monitoring of Linux boxes via SNMP. This article documents my first attempt at setting up basic Linux monitoring in Kaseya. This is new stuff for me so follow the example at your own risk!More...

Today a client had a power outage. Although the PBX in a Flash (PiaF) server was on an Uninterruptible Power Supply (UPS), the outage lasted long enough that the PiaF server crashed. Twice. Time to brave the waters of installing UPS monitoring software under Linux.
The version of PiaF that I’m using is based on CentOS 5.2, which is derived from Red Hat Enterprise Linux 5.2. APC PowerChute Business Edition supports Linux if you are using their higher-end SmartUPS line, but there is no support for BackUPS-type UPSs.More...
