Yealink VOIP issues since swapping to Superfast broadband

[andyt198]

I have been trying to resolve this issue since January, when I upgraded to superfast broadband. I wfh and my VOIP phone worked fine until then. Sky support is useless. They latest advice was to go to 192.168.0.1 and enable UPNP but still cannot make or recieve calls. The phone is connected to the wifi a I can see it on connected devices. Any help greatfully received!!

Are you using a white Max Hub?

According to AI online there's a few options, rather than post them all on here just post "Yealink VOIP phone issues using Sky Max router" in Googles AI (or any other AI), this is presuming you have a Max router. Just work your way down the options with the usual caveat that sometimes it gets it all wrong.

Nothing has worked so far, still the same issue

By default a broadband circuit with a white Max Hub will be provisioned with a shared external IP address using MAP-T: this has the potential to mess various things up (including VoIP and business VPN)

The instructions you had regarding UPnP would actually have been an attempt to switch off MAP-T and put an individual IP address in place, but this may not have been successful.

Thank you @TimmyBGood so are you saying that there is no fix?

I'd suggest you need to get Sky to confirm that you're definitely on a 1:1 IP address.

So just got off the phone with Sky who told me there's nothing they can do, cannot revert back to standard dual stack IPv4, I'll look for a provider who can support VOIP as I need it as part of my job
