ATA De-registers

[Tacitus]

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.
