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 220.127.116.11. 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 18.104.22.168. 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...

I’m setting up a new PBX in a Flash (PiaF) machine running Asterisk 22.214.171.124. I’m testing it by calling in with SJPhone across a VPN (the PiaF machine is at a client site). When I dial 7777, I get my top-level IVR, but when I press a number, nothing happens. If I dial into a voicemail box, the * and # keys have no effect. It seems PiaF is not hearing my DTMF tones at all.

After running PBX in a Flash (PiaF) in a virtual machine for a few days, I had a couple issues:
The system would generate an occasional message “TSC appears to be running slowly. Marking it as unstable.” This issue did not keep the PBX from running.
Voice quality was sometimes jittery. In a call, it would sometimes “cut out” (like a bad cell connection). In voicemail, even listening to the pre-recorded prompts, there was frequently some garbled-sounding audio.More...

In my original PBX in a Flash setup, Asterisk is set to “listen in” on calls. One advantage of this is that it can then respond to commands sent from a phone keypad during the call, e.g. to transfer or record the call. However, it does add processing overhead. If your devices support it, you can tell Asterisk to butt out of your conversations, allowing connections to “bridge” directly between endpoints and avoid going through Asterisk. Here’s how.More...
