This is the web site and the Blog are devoted to my Home Automation projects. This covers technologies such as: Ubuntu Linux, Elastix PBX, 1-wire and my own bits of software. I have recently moved to a new location on the island of Westray in Orkney (off the end of Scotland by John O’Groats).
Firstly, this was due to upgrades. Second was resolving the time synchronisation problems that have plagued me for a while. Due to the nature of how Virtual Machines are operated, maintaining time is quite difficult. With the Oracle VirtualBox, this is no exception. Time keeping on some of my VMs has been a serious issue. I tried to used NTP to resolve the problem, however the clock accuracy is so poor within the VM, that the offsets and jitters are far too large for the clock correction algorithms to correct. So an alternative solution was needed. It appears this was a well documented problem. The resolution was to make sure that I was using a version where this issue had been fixed in the Guest Additions. Continue reading HowTo: VirtualBox Guest Additions (Command Line) – Time »  Sky HD As I’m moving all my telephone apparatus over to VoIP of some sort, even if this means having to replace or use a suitable ATA (Analogu Telephone Adapter), it was time to look at the box I most feared – My trusty old Sky+ Box. I occasionally watch Sky BoxOffice, normally by recording in the middle of the night and playing it back a few days later. For this to work, the Sky box needs to be connected to a phone line. This article describes the work I completed in order to make this work with my Elastix PBX.  Stinging Nettle As I have a large field, and there appears to be a good supply of nettles both here and generally on the island. I decided that I should have a go at making some fertilizer based on the ubiquitous stinging nettle. Below is the method I’m using. For the last few weeks I have been bashing away at trying to get an inbound SIP trunk to go somewhere sensible, rather than to ‘Number not in service’ message being played to a caller. The problem is that the inbound SIP call is classified by Asterisk as an ‘Unknown Peer’ with an error message similar to: “Received incoming SIP connection from unknown peer to xxxxxxxxx”. This means that the call can’t be processed correctly. After processing the information from a selection of forums, I have come up with this solution. This article describes the changes needed to allow incoming SIP calls to be processed correctly, like any other trunk. This article does not cover SIP extensions, only SIP trunks. |
