Last month I decided to take the plunge and switch over to a Naked ADSL service. Late last year Internode had announced that they'd sorted out number porting for customers on existing ADSL2+ connections (like myself). More recently they also introduced a new tier in their Naked plans, so that leaving my old 50G ADSL2+ plan was now viable.

The switch to a naked line happened on the scheduled day. I didn't realise however that the porting of the phone number would take a few extra days. Not a huge problem, but something to be aware of.

Going naked means you have no dial-tone. If you want to keep your phone number, it needs to be ported to a VoIP service. In this case to NodePhone (Internode's VoIP offering), with $10/month call credit. I've been using first FreeCall and more recently PennyTel as outgoing VoIP providers for a number of years. It will be interesting to see how NodePhone compares.

Two nice features that I discovered was it comes with voicemail (you can customise the greeting, and you can get email notifications), and caller ID is included (instead of paying $6/month for the privilege)

I configured my trusty ATA (a Sipura SPA-3000) with new settings to work with NodePhone. All seemed fine, but it didn't work – the registration was failing. A call to Internode Support didn't identify any issues other than I was using more recent firmware than they were aware of, and that I was using relatively 'old' hardware. In any case just when I was about to give up for the evening, I noticed that it had started working all by itself.

All seemed fine for a few days, then I noticed that we were getting calls going to voicemail but no missed calls were on the phone. Strangely the ATA was still saying it was registered but most calls never rang the phone – they just redirected to voicemail.

Another call to Internode support, but again no joy. Nothing looked out of place with my settings, but they could see the registration was dropping out regularly (which would explain the calls not coming through to the handset). Their final suggestion – get some new hardware.

It turns out I bought the Sipura SPA-3000 way back in 2005. 7 years is a good innings for consumer hardware, so maybe it was time to update to something more current. The Gigaset C610 seemed to be well regarded so I picked up one from Internode's Adelaide office.

It was pretty straightforward to configure, but annoyingly I then discovered I was having the same problem still. Another call to Internode Support, but this time they said they had TWO active registrations – one for the Gigaset and one for the SPA! That didn't make sense, as the SPA was now sitting on a shelf – no power, no network. They reviewed the modem and Gigaset settings and things seemed to settle down, and I received an incoming call ok.

So hopefully that's the way things will stay for now on 😀
