ATA De-registers

Tacitus · May 02, 2026, 09:16:58

My ATA - Grandstream 801v2 - has recently started to de-register itself. A paperclip reset makes it re-register, but I really need to find a cause.

The obvious could be a faulty ATA, but putting that aside shouldn't the ATA re-register automatically in the event of a power cut or network interuption.

Anyone any ideas as to a likely cause for de-registration?

This is from a couple of years ago but there was a firmware fix to address that kind of issue. Have a read of this...

Thanks for this. Unfortunately the thing is locked down and I can't access it via a browser in the usual manner: 192.168.xx.xx etc, possibly because it's configured to use a non-standard port.

That means I can't obtain the firmware version unless I ring iDNet and I'm not sure they could tell me since UBOSS appears to be a black box. I assume it's the latest version since it's only been installed recently.

Surely if the power or the network goes down and it drops the registration, it should automatically re-connect and register when the network comes back up. A network scan shows that I can ping the ATA, but that only means it's alive but not necesssarily registered with the server.

It's probably worth asking IDNet though. I find it is, anyway, if I have an issue that isn't easily solved.

I did email them and got a reply along the lines of it could be a number of things.....

Well yes it could including a dud device, but since it's new that's probably unlikely. I was really looking for the most common causes so that I have some idea of where to look for the source of the problem.

Since iDNet were pretty non-commital I thought I would ask here in case anyone else had experienced problems.

Just checked and it's gone offline again...

There's such a thing as a "bathtub curve" for the faultiness of tech kit.

(Also glad I didn't put the VoIP here on BOSS.)

Must admit I was tempted to go elsewhere, but since the phone was already with iDNet it seemed simpler to go with UBOSS for the move to SOGEA. It is only a one month contract though so if this problem doesn't get sorted soon, I'll go elsewhere, probably to Voipfone who appear to be well regarded.

Out of interest, who did you go with for VOIP?

A&A, but that's because I'm technically minded and do like to tinker. There are a lot of things on their end you can tinker with. I also have it going through Asterisk running on the router. Once I got things working it's been boringly reliable.

(Asterisk's pjsip doesn't recognise incoming calls if DNS lookups fail when it's starting up. And they will if the router has only just been booted up and the PPPoE link isn't yet active.)

My setup is also multi-site. The phones here at Dad's can call the phones and services at my home via an IAX link on a VPN. For instance, dialling 123 gets you the speaking clock with Pat Simmons's voice (used from 1963-1985). Dialling 160 gets you "Dial a Disc" (actually my continually running jukebox).

I've yet to switch my phone line to VoIP as it's still under contract with Virgin Cable. When I move to an AltNet provider in late summer I will do that (assuming they'll still pay the termination fees).

There's a lot of info on how to set up most phones/ATAs: https://support.aa.net.uk/Category:VoIP_Phones

TBH despite remembering the delights of manually editing punch cards for an IBM mainframe with a hand punch and an ASCII code table, I'm getting to the age where I just want things to work.....

The ATA is behaving itself at present and shows as being online. I suspect it may be an intermittent fault in the network wiring between the router and the switch the ATA is connected to. It momentarily drops the link which causes the ATA to deregister. As I've said I would expect it to at least try to reconnect but this doesn't appear to be happening. To be fair though there's no way I can tell, it simply drops the connection which stays dropped until a manual reset.

If I can't sort it out I do have the option of going elsewhere and using the ATA in the FritzBox. The link to the A&A support page is very useful thank you.
