Future Proofing your house

Mauricio blogged about Telecom's NGN this morning and the discussed the issue of power failures affecting VoIP. Whereas traditional POTS/PSTN phones are powered by the switch in a VoIP environment your internet connection and phones are powered by your household power which means that if you're not running your equipment on a UPS you face an outage during power cuts.

Telecom's Trinity Project is the replacement of the existing POTS network with a 100% VoIP solution meaning that somewhere within the next 5-7 years every household in the country will be using a VoIP solution for their home phone as the existing NEC NEAX switches are retired. There is no need to replace your existing phone or household wiring as you will be able to continue to use your existing phones and an ATA which will convert your regular phone to function as a VoIP phone. People who do want to upgrade however will be able to use true VoIP phones which will offer enhanced features & functionality.

Anybody who's building a new house or modernising their house should make this Telecom PTC106
 essential reading. If you're building a new house you should be future proofing your house now. If your electrician wants to run regular phone cable and had no idea what the word structured cabling means then find a new one who does. Running structured cabling also doesn't need to cost the earth - I've run cabling in two new houses for friends lately and with a box of cat5e cable only costing around $130 for a 305m box and RG6 cable at less than $1 per metre for triple shielded it's not a huge expense. There are plenty of custom home structured cabling systems available but beware of paying big $$ to get the same solution.

Since I'm 100% VoIP at home I have a patch panel in the hallway cupboard with a 24 port switch, cable modem and Linksys PAP2 all powered off a UPS. I have 12 jackpoints around the house and my Linksys SPA921 VoIP phones and single cordless phone all run off their own standalone plug packs but I will soon be building my own PoE injectors to run my SPA921's since these phones don't support the PoE standard.

Sounds good... maybe I should "employ" you to modernise our home too! :-D

Until recently I was not convinced that VOIP was something to happen that was viable for Joe Average in the near future ... but I have changed my mind.

I tried Skype a dozen ways via straight software and then a combination of hardware and software and it was still rubbish.

I then bumped into a Linksys router (WG54PG2) that does the whole thing in hardware (similar to the PAP2 you mention) and it's great.

I still have a traditional PABX in the office (at home) with real phones for extensions.  The PABX has 4 out / in trunks:

- 2 Telecom standard land lines
- 1 VOIP in and out via XNET
- 1 VOIP in and out via MyNetFone in Aussie

From my PABX I can select to call out on either the land lines or either VOIP link.  I mainly use the XNET for outgoing calls and the quality is 90% of an average Telecom connected call.  Great.

I chose the MyNetFone for the second because I wanted "local" numbers in Sydney, Brisbane and Melbourne.  My clients there ring a local number and get diverted via VOIP into my PABX. Here it gets handled exactly like any other incoming call and can be picked up from any extension.

Wonderful !!!

I now have "local" calls all over Australia and NZ (and my clients call me for a local charge) for a total of about $40 per month.  The quality is good, the convenience is great.

Long live VOIP.

Any problems?  Yep.  The Linksys seems to drop out a lot if used straight of the box.  I tweaked a bit (changing MTU and other settings) to get it to not reset continually.  It still resets once or twice a day (which I don't THINK my older Nokia was doing) but this happens at the same time every day (5PM-6PM) so I blame Telecom overloading.
