VoIP works just fine. I have had people in home office with Linksys SPA phones hooked up to our Asterisk, since 2008 or 2009. Works very well, even back in the days with limited bandwidth.
With Carrier Grade NAT? I thought you were using IPv6.
With plain/local NAT - what I'm (main office) running is irrelevant. I don't immediately see that carrier-grade NAT (clients on private addresses) should be any issue, but I don't think I have had any opportunity to test, so maybe.
It is an issue. It is a NAT you do not control, so you can not punch a hole in the router/gateway.
My experience contradicts that. Over the years, I have handed out Linksys SPA921 VoIP telephones to four different employees, to use when working from home. There was never any need to "control" a NAT or punch a hole anywhere. The telephone device does that for you.
You probably have a STUN server somewhere.
The phone is configured for plain DHCP, so it will automatically get an address on the employee home network. It is configured to contact a tftp server to retrieve the initial config, for instance "sip123.example.com". And that's it - the telephone is now connected to our Asterisk, can be dialled internally and make internal and external calls. Note - no fiddling with anyoe's router or NAT or firewall or whatever.
The NAT is done with keep-alive traffic or with a STUN server, I don't think one works better than the other.
See? I knew you had a stun server.
As I mentioned, I am not aware of any of my installations having been behind a CGN, but I fail to see the significance. Basically, if you can browse a website from behind layers of NAT and CGN, the VoIP telephone will also work.
I think you need another stun server in that network. I'm not sure.
You can even try it yourself - I'll be happy to set up a SIP account for you, and you can use a softphone.
:-) Thanks, maybe some time. :-) What I'd like to setup is reach directly the existing but hidden VoIp of my provider. I know people do it. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
