Like most international travellers in the Internet age, during our recent travel through Europe I was confronted by the ridiculous situation that exists for mobile data access. By ridiculous I mean ridiculously expensive. Look, don't get me wrong: the technology that allows GSM/UMTS global roaming is pretty magical[1]. But it's not exactly new! It's not … Continue reading On global roaming for data

I've been using Nagios for ages to monitor the Crossed Wires campus network, but it's fallen into a little disrepair. Nothing worse than your monitoring needing monitoring... so I set about tidying it up. Network topology changes, removal of old kit, and some fixes to service checks no longer working correctly. One of the problems … Continue reading Nagios service check for IAX
It's been ages since I did an update on the main network machine here, and I bit the bullet over the weekend. 250+ packages emerged with surprisingly little trouble, and all I was left to do was build the updated kernel and reboot. I usually end up with something that doesn't restart after the reboot, … Continue reading Asterisk and a Patton SmartNode

I have an Asterisk phone system at home, and all the phones in the house are VoIP of some description (either real VoIP devices or analogue handsets through an ATA). While I haven't converted to VoIP as a replacement for PSTN, I have some connectivity … Continue reading Upgrading from Cisco

Nerd Vittles linked to this blog, which alludes to the possibility of … Continue reading Nokia SIP client: WTF?

Buoyed by the success of a colleague I introduced to Asterisk and FreePBX a little while ago, I decided to have another look at the extension configuration mode I use on our system. Check this post for a recap of the FreePBX configuration modes and my first thoughts.Last time I looked at this I thought … Continue reading Revisiting device-and-user mode in FreePBX
After a hiatus that has lasted since I first cut the phone system over to Trixbox (probably a year or more), LDAP caller-ID name lookup is working again on my Asterisk system! A lot easier to maintain than the original version I implemented ages ago, too. A bit of PHP code does the trick! I'm using FreePBX … Continue reading LDAP Caller ID again!
