HDX 4000 Gatekeeper and SIP Unregistered

Hello all,


I'm currently working with a number of HDX 4000 and HDX 6000 units which all synch up to a HDX 5000 unit.


Recently I've had a problem with a unit where it is showing as Unregistered SIP and unregistered with gatekeeper.

Ususally when something is unregistered with the gatekeeper all I need to do is reinput the login details to solve the issue however it doesn't apppear to work this time.

I'm also not quite sure what to do with this SIP issue.


Does anyone have any suggestions for resolving this issue?
