Sorry if these questions have been asked before but I've searched and can't find answers that seem to quite match.

I'm early in the process of having fibre installed and will be going with Big Pipe as the ISP. They don't do a plan with phone so I intend to sign with 2talk, for voice. I had thought that I could just plug my house phone wiring (just the wiring to the multiple phone sockets, not the outside wiring) into the phone sockets in my Netcomm NF4V router. That still seems the most likely but the Chorus guy asked if I had to plug into one of the POTS sockets on the ONT, which made me wonder. Now some posts here seem to suggest that is the case but I don't see how I could manage the SIP settings on the ONT, whilst I can (I think) do that on the router. So I still think plugging into the router is the way to go.

Now, if plugging into the router is the way to go, I started to look at the generic SIP settings given by 2talk and what I see in the admin screens of the Netcomm NF4V and I'm not absolutely certain that I can find matches for everything. Here are the settings given by 2talk:


  • Login/Username/ID: your-2talk-number
  • Authorisation Username/ID: your-2talk-number
  • Password: your-2talk-password
  • Domain/Realm:
  • Proxy:
  • Outbound Proxy:
  • Use Outbound Proxy: yes
  • Register Expires: 600
  • DMTF Mode: RFC2833 (or AVT/out of band)
The DTMF mode should be 'inband' in the case where fax machines or alarm systems are being used. There are other settings that can be configured but may differ from device to device on how these are implemented, but in general terms we usually advise customers set the following:


  • Preferred Codec: G.711a (or alaw)
  • Secondary Codec: G.711u (or ulaw)
  • Other default supported codecs: G.722, G.729a, GSM
  • T.38 support: Enabled (for fax machines or alarms)
  • Echo cancelation: Enabled (except for fax machines or alarms)
  • Silence Supression or VAD: Disabled
I think I can find settings on the NF4V for all of the above, except that I'm not sure about Login/Username/ID and Authorisation Username/ID, as I have Authentication Name (presumably this would be Authorisation Username), CID Name and CID Number. Perhaps CID Name and CID Number are both my 2talk number?

I guess I've got a couple of weeks before needing to nail this down, but I like to have all of the T's crossed, so any comments would be appreciated.

Forget the ONT. The chorus technician has been confused by his wide exposure to Spark landline provisioning.

Your RSP, BigPipe, do not purchase the ATA port service from Chorus, and therefore the ATA port is not provisioned.

Your choice of VoIP service provider relies on you configuring your own hardware. Hence you must use the RGW (you do not own the ONT nor have administrative access to it).

Ignore the Chorus guy. You were on the right track in the first place ;)

Re the settings - just use your 2talk login name for registration/auth and leave the CID stuff empty. You'll figure it out easy enough :)

You may also want to get a temporary 2talk number turned on now so you can get it all working before the big day. It won't cost you anything more than a couple of weeks hire on a local number ($5?).

Thanks, Pete. I feel a bit more comfortable now. That's a good idea about getting a 2talk account now. They do a free one and I can port my number later, so that looks like a good option.

Hmm. Well I got a 2talk account and I can make calls from the application they provide. So I started to try setting up my NF4V broadband router to set the phone ports working.

Sadly, I've been unsuccessful. I've tried all kinds of settings and even rebooted the router a couple of times but without success; the Voice status shows "Down", not "Up", for everything I've tried. The router log does show that the voice settings have changed but no other messages of any kind, so I can't figure out what is wrong.

I've used the settings they provided when I signed up:


2talk phone number: 02825554412
2talk fax number:
2talk password: *******
SIP Server:
Outbound Proxy:
No other settings are required!


These weren't as extensive as the general SIP settings shown on their web page, which I've also tried. I've tried adding other proxies (the router settings have Proxy, Outbound Proxy and Registrar Proxy) and used domain names or IP addresses. Nothing seems to work. 2talk have some setup guides, none of which are for my router but which gave me other options to try, without success.

In earlier communications with 2talk, they have said they don't have field technicians to help with this but pointed me at a reseller, Real IT Ltd, which appears to be a business support company, so would probably way too expensive. I'm hoping someone here might have some clues for me? :)

I'm going to try the 2talk ticket system but they'll probably just direct me at Real IT again.

OK, I continued fiddling with this and eventually found a combination of settings that worked. It was partially inspired by this topic, in this forum, and this article from the Netcomm site. I attach the screenshots for basic settings and advanced settings (2 screenshots for advanced), though I only changed a few settings on the advanced page. I'm not sure exactly what did the trick but I think it was setting the CID name and CID number to my 2talk number.

akshayogra: you still stuck?

Thanks, but no. As per my previous post, I managed to find some settings that worked. Just waiting for a number port before I connect to my house wiring (after pulling the current outside line), but I don't foresee any problem now.
