What are your experiences with VOIP service providers in Australia?

I am looking for information on using VOIP in my business

Hi Michael, I ran a small business primarily on VoIP for 5 years. My experience is that the larger providers have excellent QoS and service, while some of the smaller providers CAN have issues with quality. In the end, I used Engin, because it was very simple to set up using their provided voicebox, as well as allowed me to very easily move the phone line around.  While their costs were not the lowest, their service was excellent.  Another consideration is number portability. Before you sign up, check whether any phone number a VoIP provider would allocate to you can be taken ('ported') to another provider should you wish to change providers. This can be a trap. I overcame this issue in my own business by having an inbound 1300 number, which was very reasonably priced and gives your business a certain perception of professionalism. Since I was in the market the VoIP market has expanded - there are many other providers and quality should be very good. Be aware that if the VoIP service uses an internet connection that is shared with other internet use, your quality could be impacted. You should consider whether it is cost effective to have a dedicated internet connection for your VoIP service.  As always, do your research (as you are doing right now) and you should be able to come up with an appropriate solution.

Hi Michael,   It's a very broad area, however I'd be happy to answer specifically targetted questions. Below is a quick high-level rundown. Like Micha said, there are plenty of providers, however I'd recommend sticking with the larger names. Internode and Exetel would be two major ISPs I can think of that offer SIP trunks. There's more to it than that though. I have one client with an internal VoIP system that actually uses ISDN to make all their calls. This is potentially more expensive than using a SIP trunk.  Other clients just use SIP trunks. What's the difference? Well, a SIP trunk uses spare internet connectivity (there's a bit more to it, but this is the simple explanation" so it's important to ensure you have enough bandwidth. Usuallly, an ADSL2 connection wouldn't be enough and you'd want to be looking at a minimum of SHDSL, depending on the unmber of phone calls you wanted to make/receive at any given time. If you'd like to discuss more, I'm happy for have a no-obligation free discussion with you and help identify a solution that's right for your needs.     Personally, I've got an internode Nodephone service and one of my clients has 5 exetel services, none of which I can fault. regards, Andy

Thanks Andy, I currently have broadband cable with significant bandwidth so should be able to handle my current and future phone calls in the short to medium term.

Hi Michael

We have used Iinet as our Broadband and VOIP provider and run with 'naked cable' broadband so we don't have to pay for a phone line. Iinet's service is brilliant. If you do happen to experience problems, which is inevitable and call them from your mobile, they have a great call back feature, which you can enable if they are busy. Their call backs are not just limited to landlines they will call back on mobile too. Over the last 4 years we have had very few issues, and those we have had, have been rectified promptly. I would definitely recommend them.

Almost all the big broadband providers like iiNet, TPG, Engin  are also VOIP providers in Australia. You can bundle your NBN or ADSL with VOIP services, and that cost usually starts from AUD $10 a month. It may be easier to configure and may save you money when you bundle voip and internet services.

I use Telecube for my 1300 numbers which are directed through VOIP.  Works like a charm and inexpensive.  I also use clickncallnow for international calls, if I don't use Skype or Google Voice.

Happiest day of my business life was cutting the connection to Telstra.
