Hey guys I was wondering if anyone can help me figure out why we can't receive cals calls on open vfx through a netcomm nf4v router? We have recently upgraded to fibre from vdsl and have set up voip using the same settings we did on vdsl. However unlike on vdsl we can make outgoing calls just fine but are unable to receive any calls what so-ever. Is anyone able to tell me why this would be? I'm sure I'm missing some simple setting haha. I have attached photos of our current settings, thanks guys.

What ISP? Are you getting a real routable IP address from them or a natted one that starts with 100. normally?

ISP is UnlimitedInternet. IP address is starts with 100 and is dynamic (1xx.47.114.2xx) Which would make it natted? Would this make a difference? Thanks.

Yes it will affect it as the router has no idea of the real IP address its going out on, easiest answer is to request a real IP address and use it as a reason to break contract if you were not told of this limitation when signing up.

Ahh I see, that's weird tho as also had dynamic IP on vdsl and worked fine. I will buy a static IP and see if that makes a difference, thanks.

You dont need a static, you just need a real IP address that will work both ways from the internet to get things coming in to it ok. Were you with unlimited on a CGNAT connection for VDSL too?

I don't think 100.47.x.x is a CG NAT pool?... CG NAT is 100.64.0.0/10.
Then again, this is unlimited internet we are talking about so who knows what they could be doing.
I would suggest changing the 'bound interface' to tour UFB interface for starters.
Not related to inbound calls... but that is one hell of a funky dial plan for NZ.

Just noticed another couple of things...

Codecs.. G722 is irrelevant because it is an ATA. I would have g711a, 711u and then 729 in that order. disable 726.

Also not related to inbound calls, I am surprised you can make calls with the 'pstn prefix' set to 9 (unless you are dialing a 9?) should be blank.

Thanks guys, I used the settings chevrolux suggested and seems to be working fine now I think changing bound interface from Any_wan to PPP0.1 made the biggest difference. Was interesting learning about CG NAT as I never heard of that term before this thread. Once again thanks heaps you guys are the best!
