It's been working fine for months. Yesterday I changed the No Answer Time from 10 to 20 seconds. May or may not be coincidental, but the phone hasn't worked since. Calls to our landline from a mobile beep a couple of times and drop; outbound calls do similar.
In the router "Telephone Numbers" page there's a grey circle with a cross — VoIP isn't registering. Router log says "every IP of the domain has been tried, but we didn't find the correct one!" — retrying every 30s, all failing.
IDNet support has asked me to delete and re-add the config, done that (and rebooted), no change.
A few other things I've checked:
DNS resolves sbc.insmartcloud.com to 83.137.183.171 consistently (AdGuard and Google resolvers both return the same single IP, no failover).
Ping to that IP gets nothing back — but I know that might just be ICMP filtering at the SBC.
Checked from another UK line on a different ISP — same ping timeout.
check-host.net shows the IP unreachable from 54 global test nodes (again, could just be ICMP filtering).
Tracert dies at Cogent (149.14.250.234) before reaching the destination network.
The IP belongs to DRD Communications plc / QUDO platform (ASN 34967), not IDNet directly — I'm guessing it's their wholesale VoIP upstream.
Internet is otherwise fine.
Anyone else seeing this, or any ideas what to try next?
Thanks,
Chris
OK SOLVED ?!
I changed Bound Interface: from LAN to ANY_WAN and connected right away. I never even touched that setting before. :dunno:
We like people who solve their own problems! :thumb: ;D
Funnily enough, assuming this is UBOSS, I did the same with my TP Link VX230v, except I changed the ring time to 30 seconds. I then couldn't receive incoming calls, which rang once at the callers end then disconnected, and I got a weird message which I can't now remember, when I tried to make a call. I phoned IDNet and somehow my line had been 'blocked'. Chloe reset it there and then, but other than adding a couple of numbers to the block list, I've not touched any router settings since.
