Added the first entry and chose the line/account I wanted to use ("domain" on the page for some reason) and made the call - apparently successfully, until I checked the IPPBX call log which showed the call was dialled on the wrong account. When I looked back at the settings for that PB entry, the line/account was wrong, not what I selected. So I clicked the index number to edit the entry which was displayed as yet another of the lines/accounts. No matter how many times I pick the correct line, it actually saves a different line, I think just the first one in the list.

Anyway, currently it's useless if I cannot correctly set the line/account it should use. Is this a known problem with the VigorPhone, that the Phone Book is so buggy like this?
