To Host or not to Host - That is the question. Since the time SIP was commercialised, there has been a religious war raging, a fierce war with two staunch opponents - On-Prem (on-site) PBXers, and Hosted (off-site) PBXers.
There are benefits to both methods, it depends on how many channels and features you want (remember, in the world of VoIP, lines = channels), and how you are going to use them. If you run your local takeaway, then you could get away with a couple of channels, and a Hosted PBX solution would work fine if you don't need anything more than very basic PBX features, but if you need advanced features, or least cost routing capability, even unlimited voicemail storage, or have more than a couple employees, an attached warehouse, large office space, or your business is on multiple floors, then having your own local PBX phone system on-site using SIP trunking makes much more sense.
As the new decade rolls around, CounterPath, the developers of the popular VoIP softphone X-Lite, have decided to force everyone off and onto their Bria platform, previously for commercial users, but now for everyone, if you try to run X-lite, you'll get an error telling you its now End Of Life and to pop over to CounterPaths website and download Bria Solo Free which is free for home and non-commercial use, and claim is a direct replacement for X-Lite.
In previous articles, I've mentioned Grandstream UCM PBX's, as reasonably priced and time proven with Grandstream having been around since being formed in Boston USA around 2002. However, at present, Grandstream concentrate on the smaller end of town - and there's nothing wrong with that, as small business makes up over 99.99% of all businesses in Australia (and likely elsewhere), so there is indeed a huge market to be tapped into, and Grandstream appear to be on a winner.
But in the age of NBN where most POTS exchanges are being turned off (unless you're lucky enough to be in an NBN Wireless footprint where you get to keep your POTS line), SIP (VoIP) is your new and only option, so businesses like Hotels, Motels, Resorts, Aged Care/Retirement Villages and others in the medium size markets and upwards, are going to need to move towards SIP, and that's where thing's get price crazy for hardware.
Mozilla, through firefox, is as of the end of September, going to be rolling out the forcing of DoH, or DNS of HTTPS for users of firefox, with the U.S.A first on the rollout. Google and others are also following, but in a very much limited way, where as firefox, will be blanket enabled.
So why is DoH so bad you ask?
DoH is currently at least, only paired with Cloudfares DNS services, this is fraught with danger, as Cloudfare does log requests and keeps them for about one month based on their original announcement, and even if they now claim they wont be logging when its fully operational, it's still very dangerous, because it's also centralising the Internet, sending all your DNS queries to one company, as you can imagine, doing so is incredibly dangerous and wrong!
As one who is a stickler for privacy (pretty evident if you've read a few of my posts), DoH must be pretty f'ked up for me to come out against it, Mozilla claims this is all about privacy, but that's something 90% of us already have.
Need some data or phone cables and outlets installed in your home or business?
Moved into a unit complex and been told your service is active but your line is dead?
Who should you call? If you think Electrician, you may want to think some more.
Performing Telco and Data work must only be performed by a Registered Cabler, in most cases by one holding what's known as Open Registration with appropriate endorsements such as S for structured (data) cabling, F for fibre work, and C for coaxial cable (HFC) style work (this excludes Free to Air installers who do not need to be registered to install coaxial cables for TV antennas), all of which is stated on their Cabling Providers Registration card, which they must be able to produce when requested to do so.
Registration shows you are competent to perform such work, or, at least it should, but if engaging an Electrician, that might not always be the case as you are about to find out.
