sbiddle: Yes. But that's not what I'm talking about.

Orcon aren't doing VOIP over DSL. Orcon+ voice is VoIP to the cabinet and then POTS to the house - exactly the same as Telecom's VoIP to their ISAM and POTS to the house. 

Telecom's solution isn't VoIP to the ISAM and POTS to the house.  It is, as gigereejit said, delivered off an RGW (with built-in ATA).

gingereejit: What your suggesting is some sort of POTS->SIP/H.248 switching done at the DSLAM in the cabinet, such as ISAM-V like tecnology with a SIP->PSTN gateway at the CO. Which is POTS Emulation and needs an AGCF to swtch the traffic onto the underlying IMS platform

If it's SIP on the access node (e.g. DSLAM) , you don't need an AGCF.

freitasm: This was deployed by Orcon with their first LLU in Auckland months ago already - the first in the world actually.

Orcon was not the first in the world to deploy a VoIP DSLAM PSTN Emulation service.  The first to deploy Siemens to do it, maybe, but certainly not the first in the world.

I hadn't heard that Orcon had rolled this technology out yet.

They've certainly been spruiking the LLU deployed cabinets, and in fact I saw the dedicated patch panels for the orcon DSLAMs in the MDF on a tour of Wellington CENTREX last week

Any public domain media describing their H.248/SIP/IMS platform?


And the award for most acronyms made in a single post goes to... ;)

I wonder when this will eventually mean ultra-cheap calling for customers.

Existing telco's have a huge legacy revenue stream that they are unlikely to want to lose overnight so the most obvious answer to that would be never.
 
I believe to get cheap calling you will always need to look at alternative options than regular Telecom, Vodafone or TCL lines whether they be POTS of VoIP as their is no need for these 3 major players to offer dirt cheap calling rates for the bulk of their end users.

I suspect we could possibly see the end of "toll calls" as we know them once the NGN voice rollout is complete and instead paying a fixed price for all calling. This would be a good step forward if it does happen but would mean a huge cut in revenue for both Telecom and all other telco's who would be forced to follow.

Yeah, it's hard to see the consumer benefiting in terms of existing services becoming cheaper (if anything, IMS makes it easier for telcos to micro-charge the hell out of you).  IMS is a big investment in terms of equipment and training.  I think another reason why IMS adoption has been slow is that there's always going to be an initial period of "so what?" from the consumers.  It's a chicken-egg scenario in a way.  The challenge for telcos is to come up with the new services and repackaging of old services that IMS empowers them to provide, and get the return on investment from it.  There are bound to be some spectacular fizzers along the way.

Personally I'd like to see universal IM/presence and mixed media conferencing, but there are so many ways in which they could screw it up (e.g. pissing all over open standards).  The rest of the IP world may be interested to see what IMS brings to the party, but it's not going do any hand holding.

It was interesting to see the photo of Paul Reynolds in The Herald today - he has a conference phone and cordless phone and a Thomson 2 wire router.

From what I've been told (and I'm sure somebody will love to correct this if I'm wrong!) the demo was just using the VoIP ports on the Thompson and had both devices plugged in. Hardly a true sample of what most users will be experiencing with a true POTS solution or SIP service.

2WIRE and Thomson are very separate companies.  It is a 2WIRE device.

It's been pointed out here that an RG based service, not "true POTS".

Completely agree with you. What Telecom introducing here is no ordinary VoIP. It is a full blown IMS 6.1 implementation. It will be replacing every aspect of the existing PSTN network. Customers wont see any difference at first, but when they start to offer some interesting applications like presence or IP-centrex.

With Telecom your dialtone comes from a NEAX switch which is old school POTS equipment.

In a (very brief) nutshell with Telecom's NGN, Vodafone's Red network and Orcon+ your dialtone is generated by equipment that will typically be located in the cabinet and is an IP connection back to a VoIP softswitch that exists somewhere in the network. There is no analogue phone exchange like Telecom (and TCL's) existing networks.

If my understanding is correct, then as a user you shouldn't notice any difference.
