I have recently had fibre installed. For a Broadband supplier I have gone with Bigpipe. For a telco I have gone with 2 Talk. Phone (which I have had for some time and was working fine with 2Talk on the copper line) is Gigaset and Router is TP Link. I have set up my Gigaset and can make Voip calls but not receive calls. Can anyone tell me why and lead me through the solution. Thanks. Lemuzz

the issue is the TP link Router, you have to do this (well its what I use to have to do) each time it is powered off.

Big pipe uses CGNAT (basically double NAT) that can break VoIP. Your best option is to pay for a public IP.

Which is exactly what happens with double NAT. There is no inbound route to your IP because the SIP proxy thinks your IP is the public IP, not your IP which isn't routeable.

I am on bigpipe fibre with landline on 2talk (cisco spa-112).
We have a Tp-link Archer c7 router.
It all works wonderfully.

I did pay for a static iP address as I use a geo-unblocker.
Bigpipe only charge a one-off of $45 for a static iP address so it seemed like a no brainer.
I know several ISPs charge around $15 a month forever for this feature.
EDIT: I never had to make any special settings for voip in the router.

Ewwww! CGNAT? Really! 

 

*choke*

 

<makes mental note to never buy service from Bigpipe>

 

Re ISPs charging for statics; yep some do and indeed for a range of prices. But if you shop around you can get it for free! My ISP includes free static IPv4, and a free static /56 allocation of IPv6 too. They even do reverse DNS for my statics at no fee, and VoIP plans available too :)

This is not new. For the majority of users, it simply isn't an issue, and reduces costs as their IPv4 allocation is substantially reduced. For those requiring a public or static IPv4 address, this is provided for a one off fixed charge. Looking at your ISP's website, they would charge $10-$20 /month more for basically the same product. Of course, not quite comparing apples with apples, as there are a couple of additional services provided there, but quite niche services in many ways.

I never said it was new (although to be fair, CGNAT hasn't been widely deployed in NZ for very long, so it kinda is still pretty new). I just said it's sh|t. And it is! (sh|t)

 

I understand the market forces behind it just fine. But to me (and many others!), it's not real internet. It's just 'consumer-net'.

 

Peh! No thank you, sir. There are all manner of applications I find valueable which won't run on that crap.

 

I could _maybe_ consider CGNAT IPv4 if there was working public IPv6 available alongside, but I suspect in this case there isn't.

 

Can any Bigpipe users confirm if they're getting IPv6? I've noticed VF are doing it on their UFB circuits now, which is great to see...

 

But I'm getting terrible off-topic now!

Bigpipe ipv6 has been discussed on GZ - some people were doing some beta testing around June In think.

 

Probably ties into this:
