Elmeg ICT880 Update IP Address

[logley]

I am trying to update the IP Address of an Elmeg ICT880. I can change it within the Professional Configuration Utility, and then [Send] to the PBX, but the new IP Address does not seem to be applied to the PBX. I seem to remember that when changing the IP Address another step needs to be taken before an Upload can take place, but cannot seem to remember it.

Can anyone help.

Thanks

Lee.
