Skype over WiFi to keep it easy... But I hate the Android Skype app...
I dropped my POTS landline 2 years back and moved to Callcentric. We rarely use it anymore and keeping the number and our minimal calling costs around $9/month (that's actually for 2 lines). Callcentric is perfect for home use; the price is right and they have great features (I love the blacklist feature -- our spam calls are way down!).
Once you have VOIP service, you can install a SIP client on your phone. I use CSipSimple ( https://play.google.com/store/apps/details?id=com.csipsimple&hl=en ). My house phone (hiding behind a Grandstream ATA) is extension 100 and my CSipSimple client is extension 101. When I call home, i just call 100 and it works.
SIP over WiFi or GSM ain't all that great, but it works in a pinch.
I also run Jitsi on my laptop and that's a big step up if you have a good connection.
Depends on that app your using to make calls. I know that CSipSimple can be set as the default dailer but it has to be supported in the app.
When I signed up with MyRepublic they sent me a Technicolor TG789 preconfigured, I believe that iinet would've sent out the same model. All I needed to do was plug in my existing phone and it worked (not that I use it). I have no complaints with the modem.
I'd suggest returning/exchanging what you bought for a model in the whirlpool list that has a VOIP port, or if you can wait, ask iinet to send theirs out.
You can also download a VOIP client on your phone and use that, if you know the configuration - https://play.google.com/store/apps/details?id=com.csipsimple
Sì! CSipSimple per Android. È anche open-source.

Grazie per il link, quelle tariffe sono ottime!
SMS with SIP is simple.
Both CSipSimple and GS Wave support this, and both are free.
If you have a single number, then I don't know how you would decide who to send the SMS to. Get another DID, what does it cost a month a few bucks?
You can sign up for any commercial SIP provider like https://voip.ms/ or https://didlogic.com/ and add some calling credit to your account. Calling North America is typically between ¼¢ and ½¢ per minute (not free like Google is - but calling other countries is typically cheaper than Google). Then install CSipSimple https://play.google.com/store/apps/details?id=com.csipsimple&hl=en and configure it per the provider instructions (it comes with predefined config wizards for lots of providers so if you don't like either choice above it has lots more suggestions).
If you also need to receive calls you can rent a "DID" (Direct Inward Dial number) and link it to the SIP account. DIDs are usually about $1/month plus 1¢/minute of actual calls but it depends on your country and region.
Disclaimer: I don't work for any of the SIP companies but I do use voip.ms for my home phone and on my Android phone. I chose them not because they had the best prices but because they were the only ones who could port my old home phone number from Bell Canada. If you only need outbound calls or you want a new number you won't care about that.
Extra bonus: you can configure SIP clients on your desktop or laptop too and have them all on the same account, and you can also get what's called an ATA (Analog Telephone Adapter) which converts a regular landline phone into a SIP phone. They cost about US$40. The Cisco SPA112 seems to be the best one, and the SIP companies usually have instructions on how to set it up for their service.
There is an android voip client called csipsimple that, I believe, is open source (GPL) and can record calls.
FWIW, CSipSimple on Android does. https://play.google.com/store/apps/details?id=com.csipsimple&hl=en_US
>why do onsip and junctionnetworks.com not have naptr records for the domains?
A couple of reasons. Primarily, onsip.com is a UDP SIP service. Because NAPTR is a mechanism used to discover available transport protocols of SRV's to lookup, it doesn't really make a great deal of sense for us to have NAPTR records that point to a UDP SRV since UDP is by far, what the large majority of clients are setup to use by default. The second reason is again that very few clients even support NAPTR records and instead will just do SRV lookups based on the protocol they have been configured to use.
>Is it bad practice to have the root of your domain (like onsip.com) contain a naptr record?
Not at all - that is exactly what they are for, to indicate what transport protocols are available for given services for a domain.
>are you using bria on your smartphone and just keeping it registered to opensips all the time?
I have used pretty much every SIP client available for Android, I used CSipSimple for a long time, but I feel like the project has not really been kept up. I did use Bria for some time, but I find that they often break fundamental things, like DNS, with new releases. I got fed up with it breaking every other update. I have switched to using Grandstream Wave as my "daily driver" - its very full featured and free.
And yes - I have it registered 24x7.
MicroSIP for Windows (Also runs really well under Wine). CSipSimple on Android.
yea, softphone client. https://play.google.com/store/apps/details?id=com.csipsimple
For that small of a business I would consider using Asterisk and FreePBX. You can even run it on a Raspberry Pi. Installation instructions are at http://www.dslreports.com/forum/r30661088-PBX-FreePBX-for-the-Raspberry-Pi or if you want an all-in-one "install and go" package look at http://www.raspberry-asterisk.org/ (I slightly favor the first approach, but either will work). Your Polycom's should work fine with it, I think, and there are many SIP-based apps (for example, https://play.google.com/store/apps/details?id=com.csipsimple which runs on Android devices; there has to be comparable software for an iPhone) that you can use.
Note that there is a learning curve on anything you try to use but the nice thing about this setup is you can have a full working PBX for under $100 and if it doesn't work out you can always use the Raspberry Pi for something else. If it works I would just make sure to backup the SD card regularly (both of the above method include a backup script), and maybe keep a spare SD card (or even a spare Raspberry Pi) around so you can easily make a swap in the event of card failure or hardware failure. The SD card is kind of the weak link in these systems you you would want to make use you have a good one (also there are ways to hook up an external thumb drive, SSD drive or hard drive via the USB port, in that case you would use the SD card only during the bootup process but then transfer control to the external drive, to avoid excessive wear on the SD card).
I know some people will probably recommend much more expensive or difficult to implement solutions but if as you say "you're not trained in VOIP Systems" then anything you try to use will have some degree of difficulty, but running a PBX on a Raspberry Pi is probably the easiest (and least expensive) way to get your feet wet, and it really is more than adequate for a system with only 3 or 4 extensions.
