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: sip.2talk.co.nz
- Proxy: sip.2talk.co.nz
- Outbound Proxy: sip.2talk.co.nz
- Use Outbound Proxy: yes
- Register Expires: 600
- DMTF Mode: RFC2833 (or AVT/out of band)
- 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 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.
