I was setting up a new Android phone today and wanted to be able to make calls through our VoIP system (voipfone.co.uk) from it. I tried a couple of free apps but could not get the settings to work for either of them. Then I discovered this link and decided to try Zoiper, afterall I've used it before and this seemed like a clear walk-through.

After following those steps it worked first time. So if you're looking to set up a SIP client on your Android phone then this is definitely the way to go.

Unable to Eject USB HDD
We recently found that on a server the USB Hard-disk used for backups could not be ejected and therefore safely removed. This behaviour only started after AVG was installed.
Bizzarley when using Process Monitor to see what program was accessing the disk it was showing wbengine.exe and vds.exe which are both to do with Microsoft Backup. The backup was however reportedly working correctly and finished hours prior.
We went on a wild goose chase looking into why the backup process was continually running, only to find a clue in the Event Log:
The application \Device\HarddiskVolume2\Program Files (x86)\AVG\AVG9\avgchsva.exe with process id 496 stopped the removal or ejection for the device USB\VID_0930&PID_0B1A\20111130220195.
Searching for information about this resulted in the following forum post at AVG:
http://forums.avg.com/gb-en/avg-forums?sec=thread&act=show&id=33311
So it would appear that the solution is to turn the cache off, at least until AVG respond with a fix, which given that this post is from 2009, I assume the fix is not coming.
So disable the cache in this way:
- Open AVG user interface and Advanced settings.
- In left branch select "Cache Server".
- Uncheck "Caching enabled" and save settings by OK.

Kaseya Script to Silently Uninstall Symantec Endpoint Protection
When managing a number of computers you will likely find that sometimes you have to do repetitive tasks on all computers. The beauty of a management product like Kaseya is that this can all be automated. The tricky part is in creating the automation. One task that we had to do recently was install the Kaseya Endpoint Protection on all managed machines in an organisation in place of their existing product which was Symantec Endpoint Protection. Unfortunately the script does require a little bit of initial setup but will undoubtedly save you time and save the end-user time.
This is the script:
Copy and paste it into Kaseya under Procedures > Import
The thing to bear in mind is that this script requires a registry key in order to perform the uninstall. The key varies between OS and product versions so you will need to run this a few times if you have a mixed operating system environment. Prior to running, use Kaseya LiveConnect (KLC) to look up the registry key as detailed in the Symantec article below and quoted here:
*At this step you might find it easier to press F3 and search for "symantec" but this won't work in KLC.
See articles below for further details.

- In the Windows Registry Editor, expand the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
This key contains many<Product Code> keys. - In the left pane, click each <Product Code>
key.* - In the right pane, look at the DisplayName value.
- Find the
<Product Code> key whose DisplayName value is Symantec Endpoint Protection Copy this <Product Code> and paste it into Step 2 of the procedure that begins "Create variable productkey" - on the right-hand side shown in the image below as {3C1AE....etc.}
